KVM: x86/mmu: remove unused variable
The last use of 'pfn' went away with the same-named argument to
host_pfn_mapping_level; now that the hugepage level is obtained
exclusively from the host page tables, kvm_mmu_zap_collapsible_spte
does not need to know host pfns at all.
Fixes: a8ac499bb6ab ("KVM: x86/mmu: Don't require refcounted "struct page" to create huge SPTEs")
