xenoprof: flush remaining smples when sampling is stopped.

Xenoprof notifies guest kernel via VIRQ_XENOPROF when sampled.
But it does coarsly based on heuristic so that sometimes VIRQ_XENOPROF
isn't delivered resulting in that oprofile daemon collects no sample.
To avoid that situation, always send VIRQ_XENOPROF when sampling is stopped.
