osd: refuse to start if release > recorded min_osd_release + 2

If we try to start up the objectstore, we may make writeable changes to
(say) rocksdb that are not backwards compatible.  This happens, for
example, if you start a mimic osd.  Even if the compatset checks fail,
rocksdb may have written something that is not backwards compatible.
