mlxsw: spectrum_router: Replay IP NETDEV_UP on device deslavement

Browse source

When a netdevice is removed from a bridge or a LAG, and it has an IP
address, it should join the router and gain a RIF. Do that by replaying
address addition event on the netdevice.

When handling deslavement of LAG or its upper from a bridge device, the
replay should be done after all the lowers of the LAG have left the bridge.
Thus these scenarios are handled by passing replay_deslavement of false,
and by invoking, after the lowers have been processed, a new helper,
mlxsw_sp_netdevice_post_lag_event(), which does the per-LAG / -upper
handling, and in particular invokes the replay.
