    Clean up image tmp file if c-vol gets restarted

    When creating a volume from image, and then restarting
    the cinder-volume process while the image is downloading,
    cinder can't clean up the image tmp file under image
    conversion dir.

    This patch will clear all tmp files in init_host.
