Subject: [PATCH] block/mirror: Always call block_job_sleep_ns()

The mirror block job is trying to take a clever shortcut if delay_ns is
0 and skips block_job_sleep_ns() in that case. But that function must be
called in every block job iteration, because otherwise it is for example
impossible to pause the job.
