[PATCH] drm/connector: Make drm_connector_attach_hdr_output_metadata_property() return void

[Maíra Canal]

drm_connector_attach_hdr_output_metadata_property() always returns zero,
since drm_object_attach_property() returns void. No caller checks the
return value, so change the return type to void.

Also fix a typo in the kerneldoc ("HDR_OUTPUT_METADA" -> "HDR_OUTPUT_METADATA").
