xfs: validate feature support when recovering rmap/refcount/bmap intents

The bmap, rmap, and refcount log intent items were added to support the
rmap and reflink features.  Because these features come with changes to
the ondisk format, the log items aren't tied to a log incompat flag.

However, the log recovery routines don't actually check for those
feature flags.  The kernel has no business replayng an intent item for a
feature that isn't enabled, so check that as part of recovered log item
validation.  (Note that kernels pre-dating rmap and reflink will fail
the mount on the unknown log item type code.)
