There's no such thing like small_cpumask_bits. Here and everywhere,
nr_cpu_ids must be used.

Actually, before 596ff4a09b89 nr_cpumask_bits was deprecated, and it
must be like that for all users even now.

nr_cpumask_bits must be considered as internal cpumask parameter and
never referenced outside of cpumask code.
