We were using a different key for the port mapper.
During AllocatePorts, the portbindings hostIP was nil. So, the key to the port mapper was <HostIP:nil, host port, etc...>
However, during ReleasePorts, the portbindings hostIP was 0.0.0.0. So, the key to port mapper was <HostIP:0.0.0.0, host port, etc...>
Since thoe HostIP was different (nil vs 0.0.0.0), we never removed the entry from the port mapper. This resulted in us leaking all the port bindings in port mapper.
