KVM: x86/mmu: Fix NX page unaccounting for TDP MMU pages
unaccount_nx_huge_page() unconditionally passes KVM_SHADOW_MMU to
untrack_possible_nx_huge_page(), which is incorrect, particularly on
the path from kvm_recover_nx_huge_pages(), which handles pages from
both MMUs.
Fix this by passing down the MMU type from the callers. Note that
__kvm_mmu_prepare_zap_page() is only used for shadow MMU pages.
