staging: wfx: fix warning about freeing in-use mutex during device unregister
After hif_shutdown(), communication with the chip is no more possible.
It the only request that never reply. Therefore, hif_cmd.lock is never
unlocked. hif_shutdown() unlock itself hif_cmd.lock to avoid a potential
warning during disposal of device. hif_cmd.key_renew_lock should also
been unlocked for the same reason.
