3.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marcin Slusarz <marcin.slus...@gmail.com>
commit cfd376b6bfccf33782a0748a9c70f7f752f8b869 upstream.
If we return freed vm, nouveau_drm_open will happily call nouveau_cli_destroy,
which will try to free it again.
