All async events are enqueued via nvmet_add_async_event() which updates the ctrl->async_event_cmds[] array and additionally an struct nvmet_async_event is added to the ctrl->async_events list. Under normal operations the nvmet_async_event_work() updates again the ctrl->async_event_cmds and removes the corresponding struct nvmet_async_event from the list again. Though nvmet_sq_destroy() could be called which calls nvmet_async_events_free() which only updates the ctrl->async_event_cmds[] array. Add new functions nvmet_async_events_process() and nvmet_async_events_free() to process async events, update an array and the list. When we destroy submission queue after clearing the aen present on the ctrl->async list we also loop over ctrl->async_event_cmds[] for any requests posted by the host for which we don't have the AEN in the ctrl->async_events list by calling nvmet_async_event_process() and nvmet_async_events_free().
