Peter P Waskiewicz Jr 4308ad8011 genirq: Clear CPU mask in affinity_hint when none is provided ...

When an interrupt is disabled and torn down, the CPU mask returned
through affinity_hint right now is all CPUs. Also, for drivers that
don't provide an affinity_hint mask, this can be misleading. There
should be no hint at all, meaning an empty CPU mask.

[ tglx: use zalloc_cpumask_var instead of clearing it under the lock ]
