i965/gen6-7/sol: Bump primitive counter BO size.
Improves performance of SynMark2 OglGSCloth by a further 9.65%±0.59%
due to the reduction in overwraps of the primitive count buffer that
lead to a CPU stall on previous rendering. Cummulative performance
improvement from the series 81.50% ±0.96% (data gathered on VLV).
