ath9k: use software queues for un-aggregated data packets
This is a first step for improving fairness between legacy and 802.11n traffic, and it should also improve reliability of resets and channel changes by keeping the hardware queue depth very short. When an aggregation session is torn down, all packets in the retry queue will be removed from the BAW and freed. For all subframes that have not been transmitted yet, the A-MPDU flag will be cleared, and a sequence number allocated. This ensures that the next A-MPDU session will get the correct initial sequence number. This happens both on aggregation session start and stop.
