Subject: rework check_disk_change() v2

Hi Jens,

this series replaced the not very nice check_disk_change() function with
a new bdev_media_changed that avoids having the ->revalidate_disk call
at its end.  As a result ->revalidate_disk can be removed from a lot of
drivers.

Changes since v1:
 - minor changelog spelling fixes
