drm/scheduler: Essentialize the job done callback
The job done callback is called from various places, in two ways: in job done role, and as a fence callback role. Essentialize the callback to an atom function to just complete the job, and into a second function as a prototype of fence callback which calls to complete the job. This is used in latter patches by the completion code.
