More consistency and prep work for the next patch. Aside: I wonder whether we shouldn't just move this entire xarray business into the scheduler so that not everyone has to reinvent the same wheels. Cc'ing some scheduler people for this too. v2: Correctly handle sched_lock since Lucas pointed out it's needed. v3: Rebase, dma_resv_get_excl_unlocked got renamed v4: Don't leak job references on failure (Steven).
