Reduce the scope of volatile qualifiers Commit c66a7d75e652 introduced a new "cast discards ‘volatile’" warning (-Wcast-qual) in vac_truncate_clog().
Instead of making use of unvolatize(), remove the warning by reducing the scope of the volatile qualifier (added in commit 2d2e40e3bef) to only 2 fields. Also do the same for vac_update_datfrozenxid(), since the intent of commit f65ab862e3b was to prevent the same kind of race condition that commit 2d2e40e3bef was fixing.
