disk_create() now creates the devstat entry for disks, but defaults
everything to be a direct access (with no interface type).

I've got patches in progress to fix that, but it looks like things should
work with the current state of affairs.

Have you rebuilt world?

It looks like vinum(8) doesn't include a call to devstat_checkversion(), so
it's possible you've got a version mismatch but no way to know it.
