[PATCH 08/19] xsysace: use bdev_check_media_change

[Christoph Hellwig]

Switch to use bdev_check_media_change instead of check_disk_change and
call ace_revalidate_disk manually.  Given that ace_revalidate_disk 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.
