nochanges/read_only interaction nochanges means "we cannot issue writes at all"; it's possible to go into a pseudo read-write mode where we pin dirty metadata in memory, which is used for fsck in dry run mode and doing journal replay on a read only mount, but we do not want to allow an actual read-write mount in nochanges mode. But we do always want to allow early read-write, during recovery - this patch clarifies that.
