We must check whether the job is force-cancelled early in our main loop,
most importantly before any `continue` statement. For example, we used
to have `continue`s before our current checking location that are
triggered by `mirror_flush()` failing. So, if `mirror_flush()` kept
failing, force-cancelling the job would not terminate it.
Jobs can be cancelled while they yield, and once they are
(force-cancelled), they should not generate new I/O requests.
Therefore, we should put the check after the last yield before
mirror_iteration() is invoked.
