Commit "drm/nouveau: add some debug output if nouveau_mm busy at destroy time" revealed an issue where vram mm takedown would actually fail due to there still being nodes present, causing nouveau to leak a small amount of memory on module unload. This splits TTM/nouveau_mm a bit more cleanly and ensures nouveau_mm fini isn't done until all gpuobjs are also destroyed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
