Revert "KVM: x86/mmu: Zap only TDP MMU leafs in kvm_zap_gfn_range()"
This reverts commit cf3e26427c08ad9015956293ab389004ac6a338e.
Multi-vCPU Hyper-V guests started crashing randomly on boot with the
latest kvm/queue and the problem can be bisected the problem to this
particular patch. Basically, I'm not able to boot e.g. 16-vCPU guest
successfully anymore. Both Intel and AMD seem to be affected. Reverting
the commit saves the day.
