rt2x00: Fix stuck queue in tx failure case

Since commit 0b7fde54f94979edc67bbf86b5adba702ebfefe8 "rt2x00: Protect
queue control with mutex" rt2x00 used rt2x00queue_pause_queue for
stopping a tx queue in mac80211. But in case of a failure in the tx
path rt2x00 still called ieee80211_stop_queue which stopped the queue
but prevented rt2x00queue_unpause_queue to wake the queue up again
resulting in a stuck tx queue.

Fix this by also using rt2x00queue_pause_queue in case of tx failures.
