net: bridge: fix error in br_multicast_add_port when CONFIG_NET_SWITC…
…HDEV=n commit 68f5c12 upstream. When CONFIG_NET_SWITCHDEV is disabled, the shim for switchdev_port_attr_set inside br_mc_disabled_update returns -EOPNOTSUPP. This is not caught, and propagated to the caller of br_multicast_add_port, preventing ports from joining the bridge.
