When creating an image file with a backing file, we generally try to open the backing file (unless -u was specified), mostly to verify that it is there, but also to get the file size if none was specified for the new image. For neither of these things do we need data I/O, and so we can pass BDRV_O_NO_IO when opening the backing file. This allows us to open even encrypted backing images without requiring the user to provide a secret. This makes the -u switch in iotests 189 and 198 unnecessary (and the $size parameter), so drop it, because this way we get regression tests for this patch here.
