vmx: reduce cpu load by eliminating nop-loop
Sacrifice some of the sub-millisecond timer precision in favor of less
cpu load when the timer is about to be kicked a bit early. Result is
visible *especially* when the guest idling.
Timer proc *still* has to send to the channel (in order to kick PIT
and RTC logic), which takes time, and compensates a bit for possibly
early runs.
