Switch to use bdev_check_media_changed instead of check_disk_change and
call idecd_revalidate_disk manually. Given that idecd_revalidate_disk
only re-reads the TOC, and we already do the same at probe time, the
extra call into ->revalidate_disk from bdev_disk_changed is not required
either, so stop wiring up the method.
