[PATCH -tip V3 8/8] workqueue: Fix affinity of kworkers when attaching into pool

From: Lai Jiangshan When worker_attach_to_pool() is called, we should not put the workers to pool->attrs->cpumask when there is not CPU online in it. We have to use wq_online_cpumask in worker_attach_to_pool() to check if pool->attrs->cpumask is valid rather than cpu_online_mask or cpu_active_ma
