drm/panfrost: Use DRM_GPU_SCHED_STAT_NO_HANG to skip the reset

Panfrost can skip the reset if TDR has fired before the free-job worker.
Currently, since Panfrost doesn't take any action on these scenarios, the
job is being leaked, considering that `free_job()` won't be called.

To avoid such leaks, inform the scheduler that the job did not actually
timeout and no reset was performed through the new status code
DRM_GPU_SCHED_STAT_NO_HANG.
