This now happens every time in system_tests_http2. The leak is currently
suppressed in {{lsan.supp}}.

> This leak is easily triggered by the HTTP1 adaptor but can also be triggered
> using plain AMQP.
> This is a shutdown leak. This occurs when a qdr_delivery_t is left on the
> link's updated_deliveries list at the point where the shutdown occurs.
> Since this is a shutdown leak I will add a suppression to the lsan.supp list
> for now - this Jira remains open until the issue is actually fixed.
