Fix unreported: Eevee Principled Shader: Crash because Intel does not like dead code

The reason for the crash is still a bit confusing, but on Windows with Intel HD Graphics 4000 it always happens when you enable `Use Nodes` or when you try to connect the Pricipled Shader node to the output without the `Subsurface Scattering` and `Subsurface Translucency` options enabled.
