In case any operation fails before we can successfully go the point where we would register a MDIO bus, we would be going to an error label which involves unregistering then freeing this yet to be created MDIO bus. Update all error paths to go to label free which is the only one valid until either the clock is enabled, or the MDIO bus is allocated and registered. This fixes kernel oops observed while trying to dereference the MDIO bus structure which is not yet allocated. Fixes: a1702857724f ("net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.")
