i965/blorp: Only do offset hacks for fake W-tiling and IMS

Graphics / Mesa 3D Graphics Library / Mesa - Jason Ekstrand [intel.com] - 17 August 2016 16:46 UTC

Since the dawn of time, blorp has used offsets directly to get at different mip levels and array slices of surfaces. This isn't really necessary since we can just use the base level/layer provided in the surface state. While it may have simplified blorp's original design, we haven't been using the blorp path for surface state on gen8 thanks to render compression and there's really no good need for it most of the time. This commit restricts such surface munging to the cases of fake W-tiling and fake interleaved multisampling.
