    Common i/o layer changes:
     - Avoid de-registering a ccwgroup device multiple times.
     - Remove check for channel path objects in get_subchannel_by_schid.
       Channel patch objects are never in the bus list.
     - Avoid NULL pointer deref. in qdio_unmark_q.
     - Fix reference counting on subchannel objects.
     - Add shutdown function to terminate i/o and disable subchannels at reipl.
     - Remove all ccwgroup devices if the ccwgroup driver is unregistered.
