[Mesa-dev] [PATCH 03/12] isl/gen8+: Allow 3D auxiliary surfaces

[Topi Pohjolainen]

Otherwise once mcs buffer gets allocated without delay for
lossless compression (same as we do for msaa), assert starts
to fire in piglit case: tex3d. The test uses depth of one
which is in fact supported even now.
