Lionel Landwerlin 5ecc1fb189 brw: always write the VUE header
In 35df3925ca ("brw: ensure VUE header writes in HS/DS/GS stages") I
misread the PRMs and thought that the VF would initialize the header.

What actually happens is that the VF does not write valid values in
there and the PRMs explicitly say that the VS shader should overwrite
whatever is in there.

We could avoid writing the header in some cases when no HW is going to
read back the header. For example with rendering disables through
3DSTATE_STREAMOUT::RenderingDisable. But those cases are dynamic and
the compiler is not able to tell. So just always write the header.
