If the time stamp counter goes backwards, a guest delay loop can become infinite. This can happen if a vcpu is migrated to another cpu, where the counter has a lower value than the first cpu. Since we're doing an IPI to the first cpu anyway, we can use that to pick up the old tsc, and use that to calculate the adjustment we need to make to the tsc offset.
