That solves the case where lhost does not support ipv6 but rhost does,
but there is still case where lhost does support it but rhost does not,
to fix that we have to clear TST_NET_IPV6_ENABLED in the
tst_net_detect_ipv6() as well.

	if [ $ret -eq 0 ]; then
		TST_NET_IPV6_ENABLED=1
	else
		TST_NET_IPV6_ENABLED=0
		tst_res TINFO "IPv6 disabled on $type"
	fi
