When fixing https://bugzilla.redhat.com/show_bug.cgi?id=1043069 I realized qemuDomainBlockStats is not the only API that does not acquire a job early enough. Generally, every API that is going to begin a job should do that before fetching data from vm->def. The following 5 APIs failed to do so and moreover used the data fetched early from vm->def after starting a job. In some circumstances this can lead to a crash.
