Comment 1 for bug 2002606

This seems to be valid bug exist on master too. At [1] the driver looks up the original image to get the image_metadata but I think we are stashing that in the instance already so instance.image_meta could be used. But we need to make sure that instance.image_meta is not updated before this point to the rescue image's metadata.

Making this as VALID. Feel free to propose patch to fix this.
