We set job->user_paused to false, and then call job->driver->user_resume(). In the case of blockjobs, this is the block_job_user_resume() function. In that function, we assert that job.user_paused is set to true. Unfortunately, right before calling this function, it has explicitly been set to false. The fix is pretty simple: set job->user_paused to false only after the job user_resume() function has been called.
