Subject: [PATCH] ath10k: wake up offchannel queue properly
Once HTT Tx queue got full offchannel queue was
stopped and never woken up again. This broke, e.g.
P2P. This could be reproduced after running a lot
of traffic enough to saturate 100% of the driver
Tx queue and then trying to send offchannel
traffic.
Fixes: 96d828d45e16 ("ath10k: rework tx queue locking")
