[Mesa-dev] [PATCH] radv: fix stencil only clears.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

If we are clearing stencil only, we still need to provide a
a valid Z output from the vertex shader.

I'm not 100% sure if this is the super correct fix, but it
does fix:
dEQP-VK.renderpass.simple.stencil
since I added S8 support.
