If we release a midcomms node structure there should be nothing left inside the dlm midcomms send queue. However sometimes we have this case because I believe some DLM_FIN message didn't got acked... if we run into a timeout handling then we should be sure there is no pending send dlm message inside this queue when releasing midcomms node structure.
