[PATCH] KVM, x86/mmu: Fix the comment around kvm_tdp_mmu_zap_leafs()

[Kai Huang <kai.huang@intel.com>]

Now kvm_tdp_mmu_zap_leafs() only zaps leaf SPTEs but not any non-root
pages within that GFN range anymore, so the comment isn't right.

Fixes: f47e5bbbc92f ("KVM: x86/mmu: Zap only TDP MMU leafs in zap range and mmu_notifier unmap")
