When creating a Snapshot with the new NewSnapshotByID() function, the
name of the RBD-image that is created is the same as the name of the
Snapshot. The `RbdImageName` points to the name of parent image, which
causes deleting the Snapshot to delete the parent image instead.
Correcting the `RbdImageName` and setting it to the `RbdSnapName` makes
sure that upon deletion, the Snapshot RBD-image is removed, and not the
parent image.
