Subject: [PATCH AUTOSEL 6.6 237/294] wifi: mac80211: don't unconditionally call drv_mgd_complete_tx()

From: Johannes Berg <johannes.berg@...el.com>

[ Upstream commit 1798271b3604b902d45033ec569f2bf77e94ecc2 ]

We might not have called drv_mgd_prepare_tx(), so only call
drv_mgd_complete_tx() under the same conditions.
