netfilter: ctnetlink: fix echo if not subscribed to any multicast group
This patch fixes echoing if the socket that has sent the request to create/update/delete an entry is not subscribed to any multicast group. With the current code, ctnetlink would not send the echo message via unicast as nfnetlink_send() would be skip. Signed-off-by:Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by:
