Dave Airlie had at least the refcount leak fixed in a later patch (but
that patch does other things which need a bit more work). But we still
have the trouble that silly userspace could hit the WARN_ON in
drm_mode_object_find.
Fix this all up to make sure we don't leak objects, and don't spew
into demsg.
Fixes: d0f37cf62979 ("drm/mode: move framebuffer reference into object.")
Testcase: igt/kms_addfb_basic/invalid-*-prop*

Slipped through the cracks in my review. The one issue I spotted
is that drm_mode_object_find now acquires references and can be
used on FB objects, which caused follow-on bugs in get/set_prop ioctls.
Follow-up patches will fix that.

One cannot rename the struct at this point, so might as well remove the
comment.
