realtek: pcs: rtl931x: don't return error on USXGMII setup

Configuring USXGMII on RTL931X was disable because it is not setup
properly right now. Affected devices need to rely on U-boot setup for
now. However, it is not the proper way to return an error in case we
just want to skip USXGMII configuration. Thus, just return 0 in that
case indicating it is properly configured.
