ath5k: remove some unneeded error handling code
th5k_hw_setup_tx_queue() returns a valid offset into the ah->ah_txq[]
array. The ah->ah_txq[] and the ah->txqs[] array are the same size.
Both have AR5K_NUM_TX_QUEUES elements. So this error handling code
will never trigger.
Also it's wrong. The call to ath5k_hw_release_tx_queue() with a qnum
of AR5K_NUM_TX_QUEUES or more will just trigger a WARN_ON() and
return. Or if it missed the WARN_ON(), it would just corrupt some
memory and return.
