That might be nice to have, but the kfree check was there to catch
people who were trying to be "tricky", and they will not be running with
that debug option enabled.

I'll just remove it, and rely on the documentation and public
humiliation instead of kernel warnings to try to enforce this rule.
It's worked pretty good so far with the kobject rules :)
