Allan Stephens 431697eb60 tipc: Prevent null pointer error when removing a node subscription ... Prevents a null pointer dereference from occurring if a node subscription is triggered at the same time that the subscribing port or publication is terminating the subscription. The problem arises if the triggering routine asynchronously activates and deregisters the node subscription while deregistration is already underway -- the deregistration routine may find that the pointer it has just verified to be non-NULL is now NULL. To avoid this race condition the triggering routine now simply marks the node subscription as defunct (to prevent it from re-activating) instead of deregistering it. The subscription is now both deregistered and destroyed only when the subscribing port or publication code terminates the node subscription.
