loop: let set_capacity_revalidate_and_notify update the bdev size
to the 5.10-stable tree which can be found at:

loop: let set_capacity_revalidate_and_notify update the bdev size
[ Upstream commit 3b4f85d02a4bd85cbea999a064235a47694bbb7b ]
There is no good reason to call revalidate_disk_size separately.
