mlxsw: spectrum_router: Veto unsupported RIF MAC addresses
On NETDEV_PRE_CHANGEADDR, if the change is related to a RIF interface,
verify that it satisfies the criterion that all RIF interfaces have the
same MAC address prefix, as indicated by mlxsw_sp.mac_mask.
Additionally, besides explicit address changes, check that the address
of an interface for which a RIF is about to be added matches the
required pattern as well.
