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.
