ath9k: fix sequence number assigment for non-AMPDU QoS data frames

wireless-testing commit 04caf863
('ath9k: more tx setup cleanups') merged tx path code for HT vs
non-HT frames, however it did not pass the tid pointer to
ath_tx_send_normal, causing an inconsistency between AMPDU vs
non-AMPDU sequence number handling.
Fix this by always passing in the tid pointer for all QoS data frames.
