rt2800usb:fix efuse detection
From: Michael Braun <michael-dev@fami-braun.de>
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) currently does not
load. One thing observed is that the vendors driver detects EFUSE mode
for this device, but rt2800usb does not. This is due to rt2800usb
lacking a check for the firmware mode present in the vendors driver,
that this patch adopts for rt2800usb.
With this patch applied, the 'RF chipset' detection does no longer fail.

rt2800usb:fix hang during firmware load
From: Michael Braun <michael-dev@fami-braun.de>
The device 057c:8501 (AVM Fritz! WLAN v2 rev. B) boots into a state that does not actually require loading a firmware file.
The vendors driver finds out about this by checking a firmware state
register, so this patch adopts this here.
Finally, with this patch applied, my wifi dongle actually becomes
usefull (scan + connect to wpa network works).
