Implement the following utility APIs.

 workqueue_set_max_active() : adjust max_active of a wq
 workqueue_congested() : test whether a wq is contested
 work_cpu() : determine the last / current cpu of a work
 work_busy() : query whether a work is busy

* Anton Blanchard fixed missing ret initialization in work_busy().
