Using tcp, after a session release and free, the session can remain attached to the list of sessions with a response message waiting for a commit (ds->waiter). This results to a use after free of this session. Also, on some error path and after free, a session could remain attached to the lists of available idle/free sessions (ds->list). This patch ensure to remove the session from those external lists before a free. This patch should be backported to all version including the dns over tcp (2.4)
