drm/amdgpu: drop redundant sched job cleanup when cs is aborted
commit 1253685f0d3eb3eab0bfc4bf15ab341a5f3da0c8 upstream.
Once command submission failed due to userptr invalidation in
amdgpu_cs_submit, legacy code will perform cleanup of scheduler
job. However, it's not needed at all, as former commit has integrated
job cleanup stuff into amdgpu_job_free. Otherwise, because of double
free, a NULL pointer dereference will occur in such scenario.
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/2457
Fixes: f7d66fb2ea43 ("drm/amdgpu: cleanup scheduler job initialization v2")
