Well as it is we have no hotplug events in netdev_run_todo at
all.  They're all in unregister_netdevice which is where they
should be and that runs under the RTNL.

In fact it would be a bug if we had anything in netdev_run_todo
tied to sysfs because once we get here we've relinquished our
ownership of the device name so someone else is free to readd
a device with the same name.

Cheers,
