ctdb-tcp: Only mark a node connected if both directions are up
Nodes are currently marked as up if the outgoing connection is
established. However, if the incoming connection is not yet
established then this node could send a request where the replying
node can not queue its reply. Wait until both directions are up
before marking a node as connected.
