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". Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
