[PATCH v4 08/10] drm/sched: Submit job before starting TDR

[Matthew Brost]

If the TDR is set to a value, it can fire before a job is submitted in
drm_sched_main. The job should be always be submitted before the TDR
fires, fix this ordering.

v2:
  - Add to pending list before run_job, start TDR after (Luben, Boris)
