The current A-MPDU tx_status report mechanism is too inaccurate.
With this patch BlockACK frames show now up to the driver and
can be processed.

This patch is a back-port from aggregation testing code.

In the past, we didn't limit the amount of active tx urbs.
However, ar9170 only has a limited buffer reserved for
pending data frames.

This wasn't much of a problem with the slower 802.11b/g.
We simply stopped the full queue and moved on to something different
in the mean time. But - as you guessed it -  this simple approach
stands in way for a decent aggregation implementation.

Otus uses slightly different set of "Minimum MPDU Start Spacing" values
than the 802.11n D2.0 specifies. (the whole table is shifted by one and
therefore the 16us spacing is not officially available!)

And while we're at it, we also initialize our MAC's density register.
So, this annoying _feature_ will not break TX A-MPDU later.

With this patch ar9170 is capable of receiving aggregated 802.11n frames
and sniffing on most networks without having a "debug message overhead".

This patch simplifies the tx_status report code by using four tx_queues per
station instead of only one. (the skb lookup should be in O(1) now :-p ).

Also, it fixes a really obvious copy&paste bug in the janitor work code and
adds back a few spilled bits to the hardware definition header about QoS.
