mac80211: QoS related cleanups
This * makes the queue number passed to drivers a u16 (as it will be with skb_get_queue_mapping) * removes the useless queue number defines * splits hw->queues into hw->queues/ampdu_queues * removes the debugfs files for per-queue counters * removes some dead QoS code * removes the beacon queue configuration for IBSS so that the drivers now never get a queue number bigger than (hw->queues + hw->ampdu_queues - 1) for tx and only in the range 0..hw->queues-1 for conf_tx.
