[PATCH 6/7 V2] workqueue: reuse wq_update_unbound_numa_attrs_buf as temporary attrs

tmp_attrs is just temporary attrs, we can use wq_update_unbound_numa_attrs_buf for it like wq_update_unbound_numa(); This change also avoids frequently alloc/free the tmp_attrs when the low level cpumask is being updated. Signed-off-by: Lai Jiangshan --- kernel/workqueue.c | 15 +--
