slirp: Check qemu_socket() return value in udp_listen()
Check the return value from qemu_socket() rather than trying to
pass it to bind() as an fd argument even if it's negative.
This wouldn't have caused any negative consequences, because
it won't be a valid fd number and the bind call will fail;
but Coverity complains (CID 1005723).
