Fix ephemeral port leak.
Fix a bug where udp.(*endpoint).Disconnect [accessible in gVisor via
epsocket.(*SocketOperations).Connect with AF_UNSPEC] would leak a port
reservation if the socket/endpoint had an ephemeral port assigned to it.
glibc's getaddrinfo uses connect with AF_UNSPEC, causing each call of
getaddrinfo to leak a port. Call getaddrinfo too many times and you run out of
ports (shows up as connect returning EAGAIN and getaddrinfo returning
EAI_NONAME "Name or service not known").
