    Assign local variable in api.v2.image_data

    If local variable 'image' will be not initialized we get UnboundLocalError
    while handle following exceptions:
    exception.StorageFull
    exception.StorageQuotaFull
    exception.ImageSizeLimitExceeded
    exception.StorageWriteDenied
    webob.exc.HTTPError
    ValueError

    This is because not initialized variable 'image' used as argument of
    method _restore. That is why we should initialize it.

    Closes-Bug: #1310952
