Therefore, calling 'blockdev-job-finalize' a second time on an already concluded job causes an assertion failure. Remove job->txn from the assertion in block_job_finalize() to fix this. block_job_do_finalize() still has the same assertion, but if a job is already removed from its transaction, block_job_apply_verb() will already error out before we run into that assertion.
