This reverts commit 9faf65fb.

It bit people like Michal Piotrowski:

  "My system is too secure, I can not login :)"

because it changed how CONFIG_NETLABEL worked, and broke older SElinux
policies.

As a result, quoth James Morris:

  "Can you please revert this patch?

   We thought it only affected people running MLS, but it will affect others.

   Sorry for the hassle."
