                MDEV-8046: Server crashes in pfs_mutex_enter_func on select from I_S.INNODB_TABLESPACES_ENCRYPTION if InnoDB is disabled

                Problem was that information schema tables innodb_tablespaces_encryption and
                innodb_tablespaces_scrubbing where missing required check is InnoDB enabled
                or not.
