[NETFILTER]: Keep conntrack reference until IPsec policy checks are done
Keep the conntrack reference until policy checks have been performed for IPsec NAT support. The reference needs to be dropped before a packet is queued to avoid having the conntrack module unloadable. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
