ddraw: Return the right error if range color keys are used.

Can you give this patch a try? It changes the error handling if a range color
key is used to match the behavior of my Geforce 7300 driver, which doesn't
support color keys.

If this doesn't fix the game: Which GPU are you running it on Windows? I
haven't found a GPU that supports range color keys on Windows yet. (Tested a
few Nvidia and AMD ones)
