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).
