target: don't always say "ipv6" as address type
"lstat->last_intr_fail_ip_addr" is an array inside the "lstat" struct.
It's never NULL so we always print "ipv6\n" here. The test should be
"if (lstat->last_intr_fail_ip_family == AF_INET6)".
We don't need the temporary buffer either. We could print directly into
"page".
