ath9k: fix tx status reporting

Browse source 
This patch fixes a bug in ath9k's tx status check, which
caused mac80211 to consider regularly transmitted unicast frames
as un-acked.
When checking the ts_status field for errors, it needs to be masked
with ATH9K_TXERR_FILT, because this field also contains other fields
like ATH9K_TX_ACKED.
Without this patch, AP mode is pretty much unusable, as hostapd
checks the ACK status for the frames that it injects.
