Since ath9k reports airtime usage directly using the ieee80211_report_airtime() callback, it shouldn't also report it using the tx_time in status. Make sure the field is zeroed before TX status is reported to avoid spurious airtime being accounted by bits being left over from earlier uses of the cb.
