Prepare the drivers which support LAG offload but don't have support for
switchdev object replay yet, i.e. the mlxsw and prestera drivers, to
deal with bridge switchdev objects being replayed on the LAG bridge port
multiple times, once for each time a physical port beneath the LAG calls
switchdev_bridge_port_offload().
