From: Rob Clark <robdclark@chromium.org>

Inspired by https://lore.kernel.org/dri-devel/20200604081224.863494-10-daniel.vetter@ffwll.ch/
it seemed like a good idea to get rid of memory allocation in job_run()
by embedding the hw dma_fence in the job/submit struct.

Applies on top of https://patchwork.freedesktop.org/series/93035/ but I
can re-work it to swap the order.  I think the first patch would be
useful to amdgpu and perhaps anyone else embedding the hw_fence in the
struct containing drm_sched_job.

  dma-buf/dma-fence: Add dma_fence_init_noref()
  drm/msm: Embed the hw_fence in msm_gem_submit
