anv: Disable the vertex cache when tessellating on SKL GT4

I have no idea if I'm correct about what's going wrong or if this is the
correct fix.  However, in my multiple weeks of banging my head on this
hang, a VUE reference counting bug seems to match all the symptoms and
it definitely fixes the hang.
