Adds 'ioctl' as a valid IO type for device error injection, so we can simulate a flush error (which OpenZFS currently ignores, but that's by the by). To support this, adding ZIO_STAGE_VDEV_IO_DONE to ZIO_IOCTL_PIPELINE, since that's where device error injection happens. This needs a small exclusion to avoid the vdev_queue, since flushes are not queued, and I'm assuming that the various failure responses are still reasonable for flush failures (probes, media change, etc). This seems reasonable to me, as a flush failure is not unlike a write failure in this regard, however this may be too aggressive or subtle to assume in just this change. Sponsored-by: Klara, Inc.
