You can keep only the for_each_online_cpu() loop and remove the other
one. And in that one also, you don't have to do this for every cpu...

something like this will help you...

cpus_processed = NULL;

for_each_online_cpu(cpu) {
    if cpu-is-present-in cpus_processed
        continue;

    cpu-set-mask(cpus_processed, policy->cpus);

}

Syntax is poor, please choose the correct one.
