HID: hid-asus: add const to read-only outgoing usb buffer 

[ Upstream commit 06ae5afce8 ]

In the function asus_kbd_set_report the parameter buf is read-only
as it gets copied in a memory portion suitable for USB transfer,
but the parameter is not marked as const: add the missing const and mark
const immutable buffers passed to that function.
