Since commit 48720ba56891 ("virtio/s390: use DMA memory for ccw I/O and
classic notifiers") we were supposed to make sure that
virtio_ccw_release_dev() completes before the ccw device, and the

Before that commit it used to be OK to delay cleaning up the memory
allocated by virtio-ccw indefinitely (which isn't really intuitive for
guys used to destruction happens in reverse construction order).
