[S390] cio: Use ccw_dev_id and subchannel_id in ccw_device_private
Use the proper structures to identify device and subchannel. Change get_disc_ccwdev_by_devno() to get_disc_ccwdev_by_dev_id(). Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
