Coleman Kane 59b6872327 Linux 5.10 compat: revalidate_disk_size() added
A new function was added named revalidate_disk_size() and the old
revalidate_disk() appears to have been deprecated. As the only ZFS
code that calls this function is zvol_update_volsize, swapping the
old function call out for the new one should be all that is required.
