All the callers of ieee80211_mgd_probe_ap_send return right after they call the flush() callback. This means that calling flush() is uneeded since its meaning is to wait until the queues of the device are empty. It is pointless to wait if there is nothing that must ensure that the frame has left the Tx queue. ieee80211_mgd_probe_ap_send is called at the very end of a worker - so flush() is not needed.
