staging: mei: unlock dev->device_lock mutex on error path in mei_open()
mei_open() acquires dev->device_lock mutex and try to allocate mei_cl,
but if the allocation fails it goes to return statement. As a result
dev->device_lock left locked.
The patch fixes goto to unlock dev->device_lock mutex on this path.
