[PATCH] KVM: Fix stale gfn_to_pfn() reference in kvm_invalidate_memslot() comment

[Jun Miao]

Commit 06cdaff80e50 ("KVM: Drop gfn_to_pfn() APIs now that all users are
gone") removed gfn_to_pfn(), but kvm_invalidate_memslot() still references
gfn_to_pfn() when describing how sp->gfn is validated for guest memory
accesses.

Update the comment to reference __kvm_faultin_pfn(), which is the actual path
involved here.

No functional change intended.
