workqueues: Improve schedule_work() documentation

Two important aspects of the schedule_work() function are not
yet documented:

 - that it is allowed to pass a struct work_struct * to this
   function that is already on the kernel-global workqueue;

 - the meaning of its return value.

The patch below documents both aspects.
