KVM: x86: Drop @vcpu parameter from kvm_x86_ops.hwapic_isr_update()
Drop the unused @vcpu parameter from hwapic_isr_update(). AMD/AVIC is
unlikely to implement the helper, and VMX/APICv doesn't need the vCPU as
it operates on the current VMCS. The result is somewhat odd, but allows
for a decent amount of (future) cleanup in the APIC code.
No functional change intended.
