    Fix image download to volume for iso images

    After changes made in
      b1ebfa4f qemu_img_info: Don't autodetect source format

    ISO image downloads from Glance fail because Cinder
    calls "qemu-img convert -f iso" and "iso" is not a supported
    image format in qemu-img. These should be treated as raw
    images during the download process.

    This would also be true for any other image formats
    supported by Glance that qemu-img cannot convert, but that
    list does not seem to include anything that we previously
    supported with Cinder downloads. (aki/ari, ovf/ova, docker)
