bridge: add brport flags to dflt bridge_getlink
To allow brport device to return current brport flags set on port. Add returned flags to nested IFLA_PROTINFO netlink msg built in dflt getlink. With this change, netlink msg returned for bridge_getlink contains the port's offloaded flag settings (the port's SELF settings).
