mlxsw: spectrum_router: Join RIFs of LAG upper VLANs
In the following patches, the requirement that ports be only enslaved to masters without uppers, is going to be relaxed. It will therefore be necessary to join not only RIF for the immediate LAG, as is currently the case, but also RIFs for VLAN netdevices upper to the LAG. In this patch, extend mlxsw_sp_netdevice_router_join_lag() to walk the uppers of a LAG being joined, and also join any VLAN ones.
