[S390] cio: Introduce ccw_bus_type.shutdown.
Introduce a shutdown method for the ccw bus that calls the driver specific shutdown method in struct ccw_driver. Switch zfcp to the new ccw_driver shutdown method. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
