We do not quite support that properly though, we still do not create a
"cpu" network device, and there is only a single master netdev per
dsa_switch at the moment, making the secondary CPU port interfaces
impossible to overlay their backing "master" netdev with their companion
switch port statistics at the moment.
This fixes a real bug where we end-up clobbering
dsa_cpu_port_ethtool_ops as soon as there are multiple trees being
registered, and this can now happen.
