netfilter: nf_conntrack_bridge: initialize err to 0
[ Upstream commit a44af08e3d4d7566eeea98d7a29fe06e7b9de944 ]
K2CI reported a problem:
consume_skb(skb);
return err;
[nf_br_ip_fragment() error] uninitialized symbol 'err'.
err is not initialized, because returning 0 is expected, initialize err
to 0.
Fixes: 3c171f496ef5 ("netfilter: bridge: add connection tracking system")
