Correctly handle AR_MoreAggr when assembling multi-descriptor final frames.

Linux ath9k doesn't have this issue as it doesn't try queuing multi-
descriptor frames to the hardware.

Before, I was only setting the first and last descriptor in the final
frame correctly - and that was done by accident. The first descriptor in
the last sub-frame was being correctly updated by ath_tx_setds_11n();
the last descriptor in the last sub-frame was being correctly updated
by ath_buf_set_rate(). But both of those are "incorrect".

The correct behaviour is:

* AR_IsAggr is set for all descriptors for all subframes in an aggregate.
* AR_MoreAggr is set for all descriptors for all non-final sub-frames
  in an aggregate.

Ie, all descriptors in the last sub-frame of an aggregate must have this
field set to 0.

I still need to do a couple of extra passes to ensure the pad delimiter
field is being correctly handled in all descriptors in the last sub-frame.
