drm/i915: Don't clobber crtc->new_config when nothing changes When doing a nop modeset we currently leave crtc->new_config point at the already freed temporary pipe_config. That will anger the sanity checks in intel_modeset_update_state() when the nop modeset gets followed by a GPU reset on gen3/4 where the display block gets fully reinitialized during the reset. So leave crtc->new_config alone until we know a modeset is actually required.
