[lvc-project] [PATCH 1/3] wifi: ath9k: cleanup ath_txq_skb_done()

[Dmitry Antipov]

Since 'txq' argument of 'ath_txq_skb_done()' is actually
(mis|un)used, convert the former to local variable and
adjust all related users. Compile tested only.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
