cpumask: Introduce for_each_cpu_andnot()
for_each_cpu_and() is very convenient as it saves having to allocate a
temporary cpumask to store the result of cpumask_and(). The same issue
applies to cpumask_andnot() which doesn't actually need temporary storage
for iteration purposes.
Following what has been done for for_each_cpu_and(), introduce
for_each_cpu_andnot().
