Pull SCSI fixes from James Bottomley:
"Two small fixes, both in upper layer drivers (scsi disk and cdrom).
The sd one is fixing a commit changing revalidation that came from the
block tree a while ago (5.10) and the sr one adds handling of a
condition we didn't previously handle for manually removed media"
