rtnl_fdb_dump always expects an index to be returned by the ndo_fdb_dump op,
but when CONFIG_NET_SWITCHDEV is off, it returns an error.
Fix that by returning the given unmodified idx.
A similar fix was 0890cf6cb6ab ("switchdev: fix return value of
switchdev_port_fdb_dump in case of error") but for the CONFIG_NET_SWITCHDEV=y
case.
Fixes: 45d4122ca7cd ("switchdev: add support for fdb add/del/dump via
switchdev_port_obj ops.")
