Just validate the old metadata and exit. Originally the check was added to not thash the only copy of metadata, but we can achieve the same just by skipping the writing/trashing. The metadata validation should protect user from wrongly specifying new size instead of old. MFC after: 1 month Sponsored by: iXsystems, Inc.
