workqueue: Make send_mayday() take a PWQ argument directly
Make send_mayday() operate on a PWQ directly instead of taking a work item, so that rescuer_thread() now calls send_mayday(pwq) instead of open-coding the mayday list manipulation. Signed-off-by: Lai Jiangshan <jiangshan.ljs@antgroup.com> Signed-off-by: Tejun Heo <tj@kernel.org>
