i915: Enable intel_render path for points

Browse source 
The sub-pixel adjustment for points was killed off in
 commit 60d762aa62
 Author: Xiang, Haihao <haihao.xiang@intel.com>

    i915: Needn't adjust pixel centers. fix #12944

so if we don't need it in intel_tris.c we don't need it in
intel_render.c either, which means we can allow intel_render.c to render
points.

No apparent regressions on PNV in ES1 or ES2 conformance.
