wined3d: Create a VBO before returning memory.

The state manager calls GetMemory before it calls PreLoad on the VBO, and PreLoad depends on finding the VBO in the strided vertex structure. This can cause problems on the first draw which creates the vertex buffer, because the first PreLoad creates the vbo and attempts to convert with an incorrect strided structure.
