ath9k: fix missed error codes in the tx status check

My previous change added in:

 commit 815833e7ecf0b9a017315cae6aef4d7cd9517681
    ath9k: fix tx status reporting

was not checking all possible tx error conditions. This could possibly
lead to throughput issues due to slow rate control adaption or missed
retransmissions of failed A-MPDU frames.

This patch adds a mask for all possible error conditions and uses it
in the xmit ok check.
