mac80211: check if atf has been disabled in __ieee80211_schedule_txq

Check if atf has been disabled in __ieee80211_schedule_txq() in order to
avoid a given sta is always put to the beginning of the active_txqs list
and never moved to the end since deficit is not decremented in
ieee80211_sta_register_airtime()
