After commit 596ff4a09b89 ("cpumask: re-introduce constant-sized cpumask
optimizations"), when NR_CPUS <= BITS_PER_LONG, small_cpumask_bits used
a macro instead of variable-sized for efficient.If no further cpus set, the cpumask_next() returns small_cpumask_bits, it must greater than or equal to nr_cpumask_bits, so fix it to correctly.
