aio_poll doesn't poll the external nodes so this should never be true, but aio_ctx_dispatch may get notified by the events from GSource. To make bdrv_drained_begin effective in main loop, we should check the is_external flag here too. Also do the check in aio_pending so aio_dispatch is not called superfluously, when there is no events other than external ones.
