iavf: Fix deadlock in iavf_reset_task
commit e85ff9c631e1bf109ce8428848dfc8e8b0041f48 upstream.
There exists a missing mutex_unlock call on crit_lock in
iavf_reset_task call path.
Unlock the crit_lock before returning from reset task.
Fixes: 5ac49f3c2702 ("iavf: use mutexes for locking of critical sections")
