From: Johannes Berg <johannes.berg@xxxxxxxxx>
If the driver rejects WoWLAN, restart the queues before returning
to cfg80211. cfg80211 will return to mac80211, but not before it
disconnects all interfaces. If we don't start the queues, any of
the packets needed for disconnecting won't be transmitted, which
is strange. Fix that.
