mirror: Stop active mirroring after force-cancel
Once the mirror job is force-cancelled (job_is_cancelled() is true), we
should not generate new I/O requests. This applies to active mirroring,
too, so stop it once the job is cancelled.
(We must still forward all I/O requests to the source, though, of
course, but those are not really I/O requests generated by the job, so
this is fine.)
