netfilter: synproxy: fix conntrackd interaction
commit 87e94dbc210a720a34be5c1174faee5c84be963e upstream. This patch fixes the creation of connection tracking entry from netlink when synproxy is used. It was missing the addition of the synproxy extension. This was causing kernel crashes when a conntrack entry created by conntrackd was used after the switch of traffic from active node to the passive node.
