mac80211: rework the pending packets code
The pending packets code is quite incomprehensible, uses memory barriers nobody really understands, etc. This patch reworks it entirely, using the queue spinlock, proper stop bits and the skb queues themselves to indicate whether packets are pending or not (rather than a separate variable like before).
