whois close fd patch

[Loganaden Velvindron]

Hi All,

Close fd sfo & sfi before returning from whois(). 

whois() is called from within a loop before exiting.

        for (name = *argv; (name = *argv) != NULL; argv++)
                rval += whois(name, host ? host : choose_server(name, country),
                    port_whois, flags);
        exit(rval);
