net: dsa: allow port_bridge_join() to override extack message
Some drivers might report that they are unable to bridge ports by returning -EOPNOTSUPP, but still wants to override extack message. In order to do so, in dsa_slave_changeupper(), if port_bridge_join() returns -EOPNOTSUPP, check if extack message is set and if so, do not override it.
