This looks like a bug.  The Lustre code was changed to detect ZFS project
quota (which has a different function signature in ZFS 0.8) but isn't
included in the ZFS 0.7.x releases, but lost the ability to detect the old
dnode accounting function signature.

I've pushed patch https://review.whamcloud.com/32418 that should fix this.
