serial: 8250_early: Fix setup() error code

Browse source

If parsing failed to decode a valid uart addr, return -ENODEV instead
of success. Although setup_earlycon() will detect the failure anyway
(because the write() method has not been set), that behavior is not
obvious and should not be relied on.
