Specifying the cache mode for a driver without a medium is not a useful thing to do: As long as there is no medium, the cache mode doesn't make a difference, and once the 'change' command is used to insert a medium, it ignores the old cache mode and makes the new medium use cache=writethrough.
Later patches will make it an error to specify the cache mode for an empty drive. Remove the corresponding test case.
