[PATCH] mac80211: Don't stop tx queue on master device while scanning.

[John W. Linville]

From: Mattias Nissler <mattias.nissler@gmx.de>

mac80211 stops the tx queues during scans. This is wrong with respect
to the master deivce tx queue, since stopping it prevents any probes
from being sent during the scan. Instead, they accumulate in the queue
and are only sent after the scan is finished, which is obviously
wrong.
