nilfs2: accept future revisions
Compatibility of nilfs partitions is now managed with three feature sets. This changes old compatibility check with revision number so that it can accept future revisions. Note that we can stop support of experimental versions of nilfs that doesn't know the feature sets by incrementing NILFS_CURRENT_REV. We don't have to do it soon, but it would be a possible option whenever the need arises. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
