KVM: WARN if vCPU creation is in-progress when locking all vCPUs

Browse source

Now that KVM holds kvm->lock for the entirety of vCPU creation, from when
created_vcpus is incremented until the new vCPU is fully onlined, WARN if
the impossible happens and KVM somehow sees a discrepancy between the
number of vCPUs "created" and "onlined".
