[PATCH 2/2] vfio/ccw: Remove FSM Close from remove handlers

Now that neither vfio_ccw_sch_probe() nor vfio_ccw_mdev_probe()
affect the FSM state, it doesn't make sense for their _remove()
counterparts try to revert things in this way. Since the FSM open
and close are handled alongside MDEV open/close, these are
unnecessary.
