Subject: [PATCH RESEND v3 2/4] drm/atomic-helper: improve CRTC
 enabled/connectors mismatch logging message

This message reports a mismatch between new_crtc_state->enable and
has_connectors, which should be either both true or both false. However it
does not mention which one is true and which is false, which can be useful
for debugging. Add the value of both avriables to the log message.
