drm/atomic: Wire file_priv through for property changes

commit 36e4523a upstream.

We need this to make sure lessees can only connect their
plane/connectors to crtc objects they own. And note that this is
irrespective of whether the lessor is atomic or not, lessor cannot
prevent lessees from enabling atomic.
