blockjob: report a better error message
When a block job fails, we report strerror(-job->job.ret) error
message, also if the job set an error object.
Let's report a better error message using error_get_pretty(job->job.err).
If an error object was not set, strerror(-job->ret) is used as fallback,
as explained in include/qemu/job.h:
typedef struct Job {
...
/**
* Error object for a failed job.
* If job->ret is nonzero and an error object was not set, it will be set
* to strerror(-job->ret) during job_completed.
*/
Error *err;
}
In block_job_query() there can be a transient where 'job.err' is not set
by a scheduled bottom half. In that case we use strerror(-job->ret) as it
was before.
