workqueue: Always queue work items to the newest PWQ for order workqueues
To ensure non-reentrancy, __queue_work() attempts to enqueue a work
item to the pool of the currently executing worker. This is not only
unnecessary for an ordered workqueue, where order inherently suggests
non-reentrancy, but it could also disrupt the sequence if the item is
not enqueued on the newest PWQ.
Just queue it to the newest PWQ and let order management guarantees
non-reentrancy.
