Subject: [PATCH v8 06/10] drm/sched: add the drm_client_id to the drm_sched_run/exec_job events

For processes with multiple drm_file instances, the drm_client_id is
the only way to map jobs back to their unique owner.

It's even more useful if drm client_name is set, because now a tool
can map jobs to the client name instead of only having access to
the process name.
