Fix incorrect spare vdev state after replacing
After a hot spare replaces an OFFLINE vdev, the new parent spare vdev state is set incorrectly to OFFLINE. The correct state should be DEGRADED. The incorrect OFFLINE state will prevent top-level vdev from reading the spare vdev, thus causing unnecessary reconstruction.
