netfilter: nf_nat: Fix memleak in nf_nat_init
When register_pernet_subsys() fails, nf_nat_bysource should be freed just like when nf_ct_extend_register() fails. Fixes: 1cd472bf036ca ("netfilter: nf_nat: add nat hook register functions to nf_nat") Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn> Acked-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
