This is a further improvement after commit 8e671e79 ("block job:
mirror: always detach the target node upon error"). It might be
that a cancelled job ends up in concluded state without an error
being set in the result of the 'query-block-jobs' QMP command and
the target node would not be detached. To fix it, also detach the
target node when cancelling the job. This is correct even when the job
was cancelled after completion, as in that case, the drive is not
switched over to use the target node.
