From: Yajun Deng <yajun.deng@xxxxxxxxx>
[ Upstream commit 38ea9def5b62f9193f6bad96c5d108e2830ecbde ]
It should be added kfree_skb_list() when err is not equal to zero
in nf_br_ip_fragment().
v2: keep this aligned with IPv6.
v3: modify iter.frag_list to iter.frag.
Fixes: 3c171f496ef5 ("netfilter: bridge: add connection tracking system")
