KVM: MMU: store generation-number into mmio spte
Store the generation-number into bit3 ~ bit11 and bit52 ~ bit61, totally
19 bits can be used, it should be enough for nearly all most common cases
In this patch, the generation-number is always 0, it will be changed in
the later patch
[Gleb: masking generation bits from spte in get_mmio_spte_gfn() and
get_mmio_spte_access()]
