    drm/xe: Take ref to job and job's fence in xe_sched_job_arm
    
    Fixes two possible races:
    
    - Submission to hardware signals job's fence before dma_fence_get at end
      of run_job
    - TDR fires and signals fence + free job before run_job completes
    
    Taking refs in xe_sched_job_arm to job and job's fence solves these by
    ensure all refs collected before entering the DRM scheduler. The refs
    are dropped in run_job and DRM scheduler respectfully. Safe as once
    xe_sched_job_arm is called execution of job through DRM sched is
    guaranteed.
    
    v2:
     - Take job ref on resubmit (Matt Auld)
