From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Events may be queued to the pipeline handler between the pipeline
handler entering the ::stop() function, and before the call to stop the
IPA has completed.

Handle these events by dispatching all pending messages at the proxy
after the IPA has fully stopped.
