If we pause a block job and drain its BlockDriverState we want that the job remains inactive until we call block_job_resume() again. However if we pause the job while it is sleeping then it will resume when the sleep timer fires. This patch prevents that from happening by checking if the job has been paused after it comes back from sleeping.
