Description
Under certain conditions, librbd can fire concurrent completions if the object-map is enabled. It would require an object to be flagged as non-existent (and therefore complete via the librbd threadpool thread) and a librados AIO read to complete concurrently. Since this is a potential issue all the back to jewel and there are no other known places where this is causing an issue, just fix 'export' to handle the case.
