netfilter: synproxy: fix conntrackd interaction
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.
