Commit dbcbabf7da ("HID: logitech-dj: fix return value of
logi_dj_recv_query_hidpp_devices") made logi_dj_recv_query_hidpp_devices
return the return value of hid_hw_raw_request instead of unconditionally
returning 0.
But hid_hw_raw_request returns the report-size on a successful request
(and a negative error-code on failure) where as the callers of
logi_dj_recv_query_hidpp_devices expect a 0 return on success.
This commit fixes things so that either the negative error gets returned
or 0 on success, fixing HID++ receivers such as the Logitech nano receivers
no longer working.

The c52f nano receiver is a mouse only receiver. This means that it needs
some special handling compared to the c534 nano receiver:
1) It sends unnumbered mouse reports with a size of 8 bytes, so we need
to extend the unnumbered mouse report handling to support reports upto
8 bytes large
2) It mouse reports have the same high-resolution format as those from the
gaming mouse receivers
3) It can report consumer/multimedia buttons on its second interface, since
this is a mouse-only receiver these must be forwarded to the mouse child
device and not to the keyboard child-device (which will not exist)

Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10
devices, add support to logitech-dj for their receivers.
Doing so leads to 2 improvements:
1) All these devices share the same USB product-id for their receiver,
making it impossible to properly map some special keys / buttons
which differ from device to device. Adding support to logitech-dj to
see these as hidpp10 devices allows us to get the actual device-id
from the keyboard / mouse.
2) It enables battery-monitoring of these devices

We emulate the DJ functionality through the driver.
The receiver supports "fake device arrival" which behaves
like the probing of DJ devices.
A non-unifying receiver has 2 USB interfaces, the first one generates
standard keypresses and is compatible with the USB Keyboard Boot Subclass.
The second interface sends events for the mouse and special keys such as
the consumer-page keys. Events are split this way for BIOS / Windows /
generic-hid driver compatibility. This split does not actually match with
which device the event originate from, e.g. the consumer-page key events
originate from the keyboard but are delivered on the mouse interface.
To make sure the events are actually delivered to the dj_device
representing the originating device, we pick which dj_dev to forward
a "regular" input-report to based on the report-number, rather
then based on the originating interface.

Add a logi_dj_recv_queue_unknown_work helper and implement query
rate-limiting inside this helper.
The motivations behind this are:
1) We need to queue workitems for reports with no place to forward them
from more places with the upcoming non-unifying receiver support, hence
the addition of the helper function.
2) When we've missed a pairing info report (or there is a race between
the report and input-events) and the input report is e.g. from a mouse
being moved, we will get a lot of these before we've finished (re-)
querying and enumerating the devices, hence the rate-limiting.
Note this also removes the:
if (!djrcv_dev->paired_dj_devices[hidpp_report->device_index])
check previously guarding the sending of an unknown workitem, the caller
of logi_dj_recv_queue_notification already does this check before calling
logi_dj_recv_queue_notification.
