Brian Behlendorf 19697e4545 Linux 5.11 compat: revalidate_disk_size()
Both revalidate_disk_size() and revalidate_disk() have been removed.
Functionally this isn't a problem because we only relied on these
functions to call zvol_revalidate_disk() for us and to perform any
additional handling which might be needed for that kernel version.
When neither are available we know there's no additional handling
needed and we can directly call zvol_revalidate_disk().
