lapic_timer_int_injected is just a test, kvm_wait_lapic_expire()
(__kvm_wait_lapic_expire()) mayb

per-vCPU timer_advance_ns should be set to 0 if timer mode is not tscdeadline
otherwise we waste cpu cycles in the function lapic_timer_int_injected(),
especially on AMD platform which doesn't support tscdeadline mode. We can
reset timer_advance_ns to the initial value if swit
