In order to fix that, we will need to make sure that corresponding tipc_chan struct is not in use before freeing tipc_dn_chan struct. This CL introduces and implements a new callback in tipc_chan_ops struct, called handle_release, that when specified will be called while an instance of tipc_chan object is getting destroyed. This is only possible when the last reference to tipc_chan struct goes away so it is not in use anymore.
