Since its inception, the GPU scheduler can leak memory if the driver calls drm_sched_fini() while there are still jobs in flight.

The simplest way to solve this in a backwards compatible manner is by adding a new callback, drm_sched_backend_ops.cancel_job(), which instructs the driver to signal the hardware fence associated with the job. Afterwards, the scheduler can savely use the established free_job()

s/savely/safely

callback for freeing the job.

Implement the new backend_ops callback cancel_job().
