cpumask: add cpumask_clear_cpus()

Browse source

When user wants to clear a range in cpumask, the only option the API
provides now is a for-loop, like:

	for_each_cpu_from(cpu, mask) {
		if (cpu >= ncpus)
			break;
		__cpumask_clear_cpu(cpu, mask);
	}

In the bitmap API we have bitmap_clear() for that, which is
significantly faster than a for-loop. Propagate it to cpumasks.
