Comment 2 for bug 1623497

Turns out that this case is still covered because Rbd.create_image() does a redundant resize. So, while the resize described in the bug report doesn't happen, the image is still resized anyway. In fact, it's now only resized once whereas it was previously resized twice, so it's actually slightly more efficient.

I'm personally inclined to leave this alone now until the refactor lands and this all becomes a lot simpler to follow.
