As for nvme/012 and nvme/013, I observed the I/O size changes from 900m to 920m
with this patch. This condition looks better for testing point of view. Good.

On the other hand, this change for nvme/035 does not look good. It runs the
test on TEST_DEV, which may take very long time without TIMEOUT config.
