[PATCH v3 1/2] wined3d: Only use default SetPixelFormat on private windows.

[Connor McAdams]

Only use the default SetPixelFormat function if the format is unset and
the window is private. If the window isn't private, use
wglSetPixelFormatWINE, which allows for another application to change
the pixel format.
