3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@xxxxxxxxxxx>
commit ec30326ea773900da210c495e14cfeb532550ba2 upstream.
Otherwise, if queues are full during a scan, tx scheduling does not
resume after switching back to the home channel.
