[PATCH 7/7] qemuDomainGetBlockJobInfo: Work stats for unfinished pre-blockdev blockjob
If the job has finished, but we didn't yet process the completion fake
that it's still incomplete so that apps which decided to poll
qemuDomainGetBlockJobInfo rather than use events can be sure that the
XML update was completed.
