When the the Tx BA session is stopped and the HW queues aren't empty,
we stop the SW queue to drain the HW queue and then switch to the
legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state.
While in this state, we never wake the SW queue, even when the HW

Once the HW queue is really empty, we must wake the SW queue in order
