Prep work for using the scheduler dependency handling. We need to call
drm_sched_job_init earlier so we can use the new drm_sched_job_await*
functions for dependency handling here.
v2: Slightly better commit message and rebase to include the
drm_sched_job_arm() call (Emma).
v3: Cleanup jobs under construction correctly (Emma)
v4: Rebase over perfmon patch
