Remove the redundant .hwapic_irr_update() ops. If a vCPU has APICv enabled, KVM updates its RVI before VM-enter to L1 in vmx_sync_pir_to_irr(). This guarantees RVI is up-to-date and aligned with the vIRR in the virtual APIC. So, no need to update RVI every time the vIRR changes. Note that KVM never updates vmcs02 RVI in .hwapic_irr_update() or vmx_sync_pir_to_irr(). So, removing .hwapic_irr_update() has no impact to the nested case.
