Errors after allocation call ethosu_job_err_cleanup(), which frees\nthe job but leaks the uninitialized fence.\n\nA scheduler dependency error also lets ethosu_job_run() return before\ndma_fence_init(). Normal cleanup then passes a zeroed refcount to\ndma_fence_put().\n\nRelease done_fence in the common cleanup path and use\ndma_fence_was_initialized() to distinguish initialized fences from raw\nallocations.\n\n[robh: also fix goto]"
