    Fixes api samples for V2 os-assisted-volume-snapshots

    Corrects the api samples for the V2 os-assisted-volume-snapshots.
    The api samples for the create path were incorrect. This patch fixes
    them so the documentation for the API will be correct. It doesn't fix
    the input validation as it would be a backwards incompatible change.
