ath6kl: Fix AP mode connect event parsing and TIM updates
This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.
The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.

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
