KVM: x86/mmu: Separate the memory caches for shadow pages and gfn arrays

Browse source

Use separate caches for allocating shadow pages versus gfn arrays.  This
sets the stage for specifying __GFP_ZERO when allocating shadow pages
without incurring extra cost for gfn arrays.

No functional change intended.
