wifi: rt2x00: remove useless code in rt2x00queue_create_tx_descriptor()

In 'rt2x00queue_create_tx_descriptor()', there is no need to call
'ieee80211_get_rts_cts_rate()' while checking for RTS/CTS frame
since this function returns NULL or pointer to internal bitrate
table entry, and the return value is not actually used. Compile
tested only.
