Since commit 48720ba56891 ("virtio/s390: use DMA memory for ccw I/O and

virtio_ccw_release_dev() completes before the ccw device, and the
attached dma pool are torn down, but unfortunately we did not.
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).[..]
