Drop the union for the pages_{4k,2m,1g} stats. The union is no longer necessary now that KVM supports choosing a custom name for stats. Eliminating the union also would allow future commits to more easily move pages[] into common code, e.g. if KVM ever gains support for a common page table code. An alternative would be to drop pages[] and have kvm_update_page_stats() update pages_{4k,2m,1g} directly. But that's not a good direction to go in since other architectures use other page sizes. No functional change intended.
