There is a case that after AMFD send reboot order due to “out of sync window”.
 AMFD receive CLM track callback but node is not AMF member yet and delete node
 from node_id_db. Later AMFND down handler will do nothing since it cannot find
 the node. When node reboot up, AMFD continue use old msg_id counter send msg to
 AMFND cause messasge ID mismatch in AMFND then AMFND order reboot itself node.
 
 Solution: in AMFND down handler, if not found node in node_id_db, searching 
node
 in node_name_db. If found, continue proceed as normal AMFND down event.
