rt2x00: Simplify TXD handling of beacons.
The handling of tx descriptors for beacons can be simplified by updating write_tx_desc implementations of each driver to write directly to the queue entry descriptor instead of to a provided memory area. This is also a preparation for further clean ups where descriptors are properly reserved in the skb instead of fiddling with the skb data pointer.
