According to the documentation, drm_add_edid_modes
"... Also fills out the &drm_display_info structure and ELD in @connector
with any information which can be derived from the edid."

drm_add_edid_modes accepts a struct edid *edid parameter which may have a
value or may be null. When it is not null, connector->display_info and
connector->eld are updated according to the edid. When edid=NULL, only
connector->eld is reset. Reset connector->display_info to be consistent
and accurate.

Since drm_edid_is_valid() considers NULL as an invalid EDID, simplify the
code to avoid duplicating code in the case of NULL/error.
