History
Adrian Chadd 3f3a5dbd2c Ensure that we only call the busdma unmap/flush routines once, when 
the buffer is being freed.

* When buffers are cloned, the original mapping isn't copied but it
  wasn't freeing the mapping until later.  To be safe, free the
  mapping when the buffer is cloned.

* ath_freebuf() now no longer calls the busdma sync/unmap routines.

* ath_tx_freebuf() now calls sync/unmap.

* Call sync first, before calling unmap.

Tested:

* AR5416, STA mode
