[Mesa-dev] [PATCH V2] i965: Fix the region's pitch condition to use blitter

[Anuj Phogat]

intelEmitCopyBlit uses a signed 16-bit integer to represent
buffer pitch, so it can only handle buffer pitches < 32k.

Dropping few changes made in earlier patch. If region->bo->size >= 
max_gtt_map_object_size, we can't fall back to intel_miptree_map_gtt().
