Linux 6.5 compat: disk_check_media_change() was added

The disk_check_media_change() function was added which replaces
bdev_check_media_change.  This change was introduced in 6.5rc1
444aa2c58cb3b6cfe3b7cc7db6c294d73393a894 and the new function takes a
gendisk* as its argument, no longer a block_device*. Thus, bdev->bd_disk
is now used to pass the expected data.
