net: switchdev: ignore unsupported bridge flags

switchdev_port_bridge_getlink() queries SWITCHDEV_ATTR_PORT_BRIDGE_FLAGS
attributes, but a driver doesn't need to implement this in order to get
bridge link information.

So error out only on errors different than -EOPNOTSUPP.

(This is a follow-up patch for 7d4f8d8.)

Fixes: 8793d0a664a8 ("switchdev: add new switchdev_port_bridge_getlink")
