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.
