mac80211: fix crash with single-queue drivers
Larry (and some others I think) reported that with single-queue drivers mac80211 crashes when waking the queues. This happens because we allocate just a single queue for each virtual interface in case the driver doesn't have at least 4 queues, but the code stopping/waking the virtual interface queues wasn't taking this into account.
