similar to: [PATCH RFC v3 5/6] tick: get duration of the last idle loop

However, when the vCPU is onlined back, it resumes execution right after VCPUOP_down hypercall. That was OK (albeit the API for play_dead assumes that the CPU stays dead and never returns) but with commit 4b0c0f294 (tick:

The main reason is that the overhead is amplified when running inside VM. The most cost I have seen is inside idle path.
