Ville Syrjälä ea0d413094 drm/atomic: Don't pollute crtc_state->mode_blob with error pointers 
commit 439cf34c8e0a8a33d8c15a31be1b7423426bc765 upstream.

Make sure we don't assign an error pointer to crtc_state->mode_blob
as that will break all kinds of places that assume either NULL or a
valid pointer (eg. drm_property_blob_put()).
