[PATCH 04/40] nl80211: Allow Tx status for authentication frames

[Ilan Peer <ilan.peer@xxxxxxxxx>]

To support PASN authentication flow, where authentication
frames are sent by the wpa_supplicant using send_mlme() callback,
modify the logic in driver_nl80211 to also send EVENT_TX_STATUS
for authentication frames.
