Oops - don't do the clrdmask check in ath_tx_xmit_normal() - the wrong
lock may be held.
Kim reported that the TID lock wasn't held when ath_tx_update_clrdmask()
was called. Well, the underlying hardware TXQ for that TID.
I'm betting it's the cabq stuff. ath_tx_xmit_normal() can be called
for both real and software cabq. For software cabq, the real destination
txq is different to the txq. So, the lock check will fail.
