[Mesa-dev] [PATCH] i965/gen7.5: Fix missing Shader Channel Select entries on Haswell

[Abdiel Janulgue]

Probably non-intentional, but the SURFACE_STATE setup refactoring
for buffer surfaces had missed the scs bits when creating constant
surface states.

Fixes broken GLB 2.5 on Haswell where the knight's textures are missing
