[PATCH 6/7] workqueue: Remove the arguments @hotplug_cpu and @online from wq_update_pod()

[Lai Jiangshan <jiangshanlai@gmail.com>]

From: Lai Jiangshan <jiangshan.ljs@antgroup.com>

The arguments @hotplug_cpu and @online are not used in wq_update_pod()
since the functions called by wq_update_pod() don't need them.
