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

[Max Reitz]

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.

This makes test 129 pass when run in tmpfs (for me, at least).
