In most cases calling hwapic_isr_update(), actually we always
check if kvm_apic_vid_enabled() == 1, and also actually,
kvm_apic_vid_enabled()
-> kvm_x86_ops->vm_has_apicv()
-> vmx_vm_has_apicv() or '0' in svm case
So its unnecessary to recall this inside hwapic_isr_update(), here
just remove vmx_vm_has_apicv() out and follow others.
