swim: use bdev_check_media_change
Switch to use bdev_check_media_change instead of check_disk_change and
call floppy_revalidate manually. Given that floppy_revalidate only
deals with media change events, the extra call into ->revalidate_disk
from bdev_disk_changed is not required either, so stop wiring up the
method.
