D3D11: Allow no-op pixel shader output.
On HLSL 4+, the debug runtime issues a warning when we try to render
to a color output in the pixel shader that doesn't have a matching
render target bound. This happens when doing a depth or stencil-only
render pass. We only need to bind a dummy output in HLSL 3, so tighten
the workaround we had in place and fix the warning for D3D11.
