workqueue: remove the lock from wq_sysfs_prep_attrs()
Reading to wq->unbound_attrs requires protection of either wq_pool_mutex or wq->mutex, and wq_sysfs_prep_attrs() is called with wq_pool_mutex held, so we don't need to grab wq->mutex here. Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Tejun Heo <tj@kernel.org>
