RE: d3d9/tests: Don't create a Null-shader in d3d9, it will crash.

[Stefan Dösinger]

I never saw this crashing on any of my systems, so it is probably driver dependent. Which Windows driver are you using?

If the test crashes on either ATI, Nvidia or Intel it is a good idea to remove it. I don't think we should remove it if it crashes on something like VMWare or other 'noname' cards.
