KVM: lapic: mark LAPIC timer handler as irqsafe
Since lapic timer handler only wakes up a simple waitqueue,
it can be executed from hardirq context.
Also handle the case where hrtimer_start_expires fails due to -ETIME,
by injecting the interrupt to the guest immediately.
Reduces average cyclictest latency by 3us.
