Now that socreate() can never fail, we can remove the code
that was trying to handle that situation.
In particular this removes code in tcp_connect() that
provoked Coverity to complain (CID 1005724): in
closesocket(accept(inso->s, (struct sockaddr *)&addr, &addrlen));
if the accept() call fails then we pass closesocket() -1
instead of a valid file descriptor.
