Fix UPnP port mapping not working

Browse source 
Despite UPNP_AddPortMapping returning sucess status, no port mapping would actually be added at all. And that's due to a memset call in the middle of the function.
Wiping the IGDdatas struct, moving the memset to the start of the function fixes it and a port mapping is actually created/removed when a server is started/stopped.
