Subject: [PATCH] iptables-xml: Free allocated chain strings
Freeing only if 'created' is non-zero is wrong - the data was still
allocated. In fact, the field is supposed to prevent only the call to
openChain().
Fixes: 8d3eccb19a9c6 ("Add iptables-xml tool (Amin Azez <azez@ufomechanic.net>)")
Signed-off-by: Phil Sutter <phil@nwl.cc>
(cherry picked from commit 73da7fb74c1089391dac0aca70e13e5f5999ace7)
