RE: d3d9: Set IDirect3DDevice9Impl_GetVertexShader return value to NULL on error

[Stefan Dösinger]

Hi,

Please write a test for this. This behavior differs from function to
function unfortunately. Some functions do not set the value to NULL, and
some apps depend on this.

I think dlls/d3d9/tests/shader.c is a good place to put this test.
