KVM: x86/mmu: move get_guest_pgd to struct kvm_pagewalk

Browse source

Start moving page walking functionality out of kvm_mmu; the easiest
target is the callbacks.

Change the kvm_mmu_get_guest_pgd() wrapper to take a struct kvm_pagewalk
too, avoiding the MMU indirection (and associated container_of) whenever
the caller already has one.  All container_of uses need to go before
nested_mmu can be changed to a struct kvm_pagewalk, signifying that it
is not used to build page tables.
