KVM: Reset PIT irq injection logic when the PIT IRQ is unmasked
upstream commit: 4780c65904f0fc4e312ee2da9383eacbe04e61ea
While the PIT is masked the guest cannot ack the irq, so the reinject logic
will never allow the interrupt to be injected.
Fix by resetting the reinjection counters on unmask.
Unbreaks Xen.
