We recently moved "bssid" off the stack, and allocated it with kmalloc()
instead. Unfortunately, this one line was overlooked so it will copy
random data into the &tgt_network->network instead of the data we want.

In function oid_rt_pro_write_register_hdl, Adapter->ImrContent is
assigned with RegRWStruct->value but Adapter->ImrContent is never used
anywhere else. So those lines has no impact and are removed removed.
As that was the only place where ImrContent was used, so the member
variable is removed from the structure _adapter

struct ndis_wlan_bssid_ex is a doppelganger of struct wlan_bssid_ex,
and is used about a third as often.
Switch all instances to wlan_bssid_ex, and remove ndis_wlan_bssid_ex
This also gets rid of a use of typedef NDIS_802_11_RATES_EX

unused variables are removed. These variables were only assigned some
values and after that they were never being used. So they are safe to
be removed , and it has been build tested.
I left a call to r8712_read32(padapter, TCR) and
r8712_read8(padapter, SDIO_HCPWM) .
r8712_read32() and r8712_read8() is ultimately calling usb_read32()
and usb_read8() respectively. and they are again calling
r8712_usbctrl_vendorreq().
this r8712_usbctrl_vendorreq() is communicating through the usb bus
and is sending and receiving the control msg.

This code is for a completely new version of the Realtek 8192 USB devices
such as the D-Link DWA-130. The Realtek code, which was originally for
Linux, Windows XP and Windows CE, has been stripped of all code not needed
for Linux. In addition, only one additional configuration variable, which
enables AP mode, remains.
