GSDX-TextureCache: Generalize scaling equation 

Previously the dedicated custom resolution scaling equation was ignored for the second SetScale() call, generalizing the equations will also fix the DMC scaling issue on custom resolution. Also remove unnecessary checks for null on scale factors. The possibility for having a null scale factor value only exists on custom resolution and it will only happen on cases where the output circuit isn't ready yet. So the ideal way would be to handle all the required conditions of output circuit on "m_renderer->CanUpscale()" itself.
