Update libnetwork to 1b91bc94094ecfdae41daa465cc0c8df37dfb3dd to bring in a fix
for stale HNS endpoints on Windows:
When Windows Server 2016 is restarted with the Docker service running, it is
possible for endpoints to be deleted from the libnetwork store without being
deleted from HNS. This does not occur if the Docker service is stopped cleanly
first, or forcibly terminated (since the endpoints still exist in both). This
change works around the issue by removing any stale HNS endpoints for a network
when creating it.
