KVM: x86: Remove hwapic_irr_update() from kvm_x86_ops
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.
