It actually is needed, since the other hunk we only update the
connector's crtc when it has an enabled connector. It makes sense for
the staged config, since the new_crtc field is in the encoder, which
would be NULL in that case. The loop just above this one sets new_crtc
to NULL for these encoders, but for the connectors it was just more
convenient to set it here.
