EEVEE: First Buffer Drawn Incorrectly

SSS buffers are lazy initialized when needed. When shaders recompile the
SSS buffers could be incorrectly drawn. During the render passes project
we tried to fix this, but that resulted in incorrect result of the first
sample after a shader was compiled.

We revert this change knowing that we know the issue, but haven't found
a proper solution for it.
