block/replication.c: Avoid cancelling the job twice

If qemu in colo secondary mode is stopped, it crashes because
s->backup_job is canceled twice: First with job_cancel_sync_all()
in qemu_cleanup() and then in replication_stop().

Fix this by assigning NULL to s->backup_job when the job completes
so replication_stop() and replication_do_checkpoint() won't touch
the job.
