KVM: x86/mmu: Use SHADOW_NONPRESENT_VALUE for atomic zap in TDP MMU
Use SHADOW_NONPRESENT_VALUE when zapping TDP MMU SPTEs with mmu_lock held
for read, tdp_mmu_zap_spte_atomic() was simply missed during the initial
development.
Fixes: 7f01cab84928 ("KVM: x86/mmu: Allow non-zero value for non-present SPTE and removed SPTE")
