[PATCH 08/24] KVM: x86/mmu: Drop redundant trace_kvm_mmu_set_spte() in the TDP MMU

[Sean Christopherson]

Remove TDP MMU's call to trace_kvm_mmu_set_spte() that is done for both
shadow-present SPTEs and MMIO SPTEs.  It's fully redundant for the
former, and unnecessary for the latter.  This aligns TDP MMU tracing
behavior with that of the legacy MMU.

Fixes: 33dd3574f5fe ("kvm: x86/mmu: Add existing trace points to TDP MMU")
