The documentation for drm_sched_backend_ops.run_job() mentions a certain
function called drm_sched_job_recovery(). This function does not exist.
What's actually meant is drm_sched_resubmit_jobs(), which is by now also
deprecated.
Remove the mention of the deprecated function.
Discourage the behavior of drm_sched_backend_ops.run_job() being called
multiple times for the same job.
