[Qemu-devel] [PATCH] iotests: improve pause_job

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

It's possible, that job was finished during waiting. In this case we
will see error message "Timeout waiting for job to pause" which is not
very informative. So, let's check during waiting iteration that the job
exists.
