[Qemu-block] [PATCH v2 12/13] blockjob: privatize block_job_sleep_ns

[John Snow]

There's not currently any external caller of it.

Except in tests, but we'll fix that here too.

Replace usages in test cases with block_job_relax, which functions
similarly enough to be used as a drop-in replacement.

Very technically block_job_sleep_ns(job, 0) behaves differently
from block_job_relax(job, 0) in that relax may resolve to a no-op,
but this makes no difference in the test in which it is used.
