Do not fail with an empty transparent IPv4 address

Browse source 
When dockerd.exe is not stopped cleanly (such as when Windows is
restarted), the endpoints are not cleaned up. When using a transparent
network, the endpoint IPv4 address is blank. When dockerd.exe starts up
again, libnetwork restores the endpoint, which would not have been
stored on a clean shutdown of dockerd.exe. That fails because the IPv4
address is blank. This change warns instead of failing.
