intel-gtt: adjust overhead entries in intel_gtt_stolen_entries
agp/intel_gtt.c and drm/i915/i915_dma.c don't calculate this the same
way: The intel-gtt code seems to use the actual gtt size, the drm
module just the mappable. Go with the logic from the drm module because
that's the more conservative choice.
But conserve the original code in intel_gtt_total_size for later use.
