commit 065e0b64f71632f5ad7f00c102fde09c534cfbf0

ath9k: fix getting tx duration for dynack
On AR9003, tx control and tx status are in separate descriptor rings.
Tx duration is extracted from the tx control descriptor data, which
ar9003_hw_proc_txdesc cannot access.
Fix getting the duration by adding a separate callback for it.
