What Kyle meant was:
NET_LOG(ERROR) << "DisassociateTetherNetworkStateWithWifiNetwork(): Tether "
               << "network with ID " << tether_network_guid << " "
               << "not registered; could not remove association.";

And personally I would put whatever text from the last line that fits on the
second line there.

Done.

nit: Same " " issue here (but as Kyle mentioned, it's a tiny nit, this is fine
as-is, but consistency within the function at least is best).
