Being brief, this small series collects a correctness fix (#1) reported by Sashiko, a error-path fix (#2) reported by Sashiko, and a cleanup (#3) found while reading the code.
The first patch is the only notable one: a v3d submission expands into a chain of jobs (e.g. BIN + RENDER + CACHE CLEAN), but the BO list was only ever attached to the last job. Since implicit synchronization is added per-job and gated on job->bo_count, every job before the last one silently skipped implicit dependencies. In practice the RENDER job could read a buffer object while another context was still writing it. It's fixed by looking up the BOs onto every job that references them.
