The usb wifi device AVM Fritz Stick N v2b (USB 057c:8501) is listed as
supported by rt2800usb, but loading the driver fails for me (kernel 3.15-rc7
and older).

I've tested these patches using a USB 057c:8501 wifi device in client mode
(scanning + connect to WPA protected BSS + network access). With the patches
applied, the device works fine. Without, it fails.
I've also tested that USB 148f:5370 (which is another usb wifi device using the
same driver), which worked also without these patches applied, still works
after applying these patches.

v2: fix endianness and coding style. Using rt2x00usb_register_read does not
work for me.
