Currently, v3d_submit_jobs() arms and pushes each job one at a time, wiring dependencies between consecutive jobs after each push. If drm_sched_job_add_dependency() fails midway, the already-pushed jobs are scheduler-owned and will be submitted to the GPU for execution, even though the subsequent jobs won't be submitted. This breaks the atomicity of the submissions, as only some of the jobs from a submission would be submitted to the hardware, while the other part fails. Restructure v3d_submit_jobs() into three phases: (1) arm all jobs belonging to a given submission, (2) wire inter-job dependencies, and (3) push all jobs to the scheduler unconditionally. Phase (2) can fail; on failure, it marks every armed job finished fence with an error, so that run_job() callbacks skip hardware execution. This guarantees that every armed job is always pushed, either to run or to be skipped, and it also ensures the atomicity of a submission.
