controlling_process can return {error, badarg}
For gen_tcp, gen_udp and gen_sctp controlling_process/2 can return
badarg if erlang:port_connect/2 fails with badarg. This can easily
happen if the new owner is not alive but in some race condition also
when the socket is closed right before port_connect/2 (and after the
previous socket function)
This commit documents this behaviour.
