rt2x00: Correctly kill beacon queue
USB devices upload their beacon and then automatically send
it out every beacon interval. However when killing a TX queue
we only kill the URB and not the actual transmission of the beacon.
This will reset the Beacon register to prevent any beacons from
being transmitted.
