wined3d: Make sure the pixel shader is compiled.

If we're heading out of the pixelshader handler early, and a pixel
shader is in use, the pixel shader may not be compiled. The vertex
shader handler then checks if the pixel shader is dirty, and calls the
shader backend to apply the shader if it isn't.  Thus, in the case of
GLSL, the shader code could attempt to link an uncompiled shader into
the program. This isn't much of a problem because when the fog is
applied, the pixel shader is compiled and the program re-linked.
