qapi: Tidy up references to job state CONCLUDED

When talking about the job state machine, we refer to the states like
READY, ABORTING, CONCLUDED, and so forth.  Except in two places, where
we use JOB_STATUS_CONCLUDED.  Replace by CONCLUDED for consistency.

We should arguably use the JobStatus enum values instead.  Left for
another day.
