[PATCH 7/8] drm/xe: Use DRM_GPU_SCHED_STAT_RUNNING to skip the reset

[Maíra Canal]

Xe can skip the reset if TDR has fired before the free job worker. Instead
of using the scheduler internals to add the job to the pending list, use
the DRM_GPU_SCHED_STAT_RUNNING status to skip the reset and rearm the
timer.

Note that there is no need to restart submission if it hasn't been
stopped.
