Previously, these would be labeled with the "__unknown" network
interface name. This ended up causing more problems since code watching
network interfaces would try to do things with the "__unknown" network.
It also didn't help, the notifications were effectively ignored by
stashing them there and it was impossible to use "__unknwon" since it
could accumulate information from several network interfaces.
The solution in this PR is to just drop the notifications. That doesn't
change behavior for any code listening to real network interfaces. I do
not know of any use of the "__unknown" interface. Messages are logged,
but through my debug I couldn't find a reason to make more than debug
level since I think they're artifacts of asynchronous cleanup of network
interfaces.
