Adrian Chadd b3c69eef25 Atheros SuperG bug fixes, as part of hunting down kern/174283. 
The stageqdepth (global, over all staging queues) was being kept
incorrectly.  It was being incremented whenever things were added,
but only decremented during a flush.  During active fast frames activity
it wasn't being decremented, resulting in it always having a non-zero
value during normal fast-frames operation.

It was only used when checking if the aging queue should be checked;
we may as well just defer to each of those staging queue counters (which
look correct, thankfully.)

Whilst I'm here, add locking assertions in the staging queue add/remove
functions.  The current crash shows that the staging queue has one frame,
but only has a tail pointer set (the head pointer being set to NULL.)
I'd like to grab a few more crashes where these locking assertions are
in place so I can narrow down the issue between "somehow locking is
messed up and things are racy" and "the stage queue head/tail pointer
manipulation logic is subtly wrong."

Tested:

* AR5416 STA, AR5413 AP; with FastFrames enabled in the AR5416 HAL.
