rt2x00: Clean up all driver's kick_tx_queue callback functions.

All of the driver's kick_tx_queue callback functions treat the TX queue
for beacons in a special manner.
Clean this up by integrating the kicking of the beacon queue into the
write_beacon callback function, and let the generic code no longer call
the kick_tx_queue callback function when updating the beacon.
