rt2x00: Split rt2x00lib_write_tx_desc()
Split rt2x00lib_write_tx_desc() up into a TX descriptor initializor and TX descriptor writer. This split is required to properly allow mac80211 to move its tx_control structure into the skb->cb array. The rt2x00queue_create_tx_descriptor() function will read all tx control information and convert it into a rt2x00 TX descriptor information structure. After that function is complete, we have all information we needed from the tx control structure and are free to start writing into the skb->cb array for our own purposes. rt2x00queue_write_tx_descriptor() will be in charge of really sending the TX descriptor to the hardware and kicking the TX queue.
