For consistency do this also there. While at it also extend the code comment about affected platforms. I couldn't reproduce the issue on VLV fixed by this workaround, by removing the workaround from everywhere, while it's 100% reproducible on SNB using igt/gem_reset_stats/ban-ctx-render. So also add a note that it hasn't been verified if the workaround really applies to VLV/CHV.
