Yes, the convention is to either leave the module loaded with
defaults, or leave it unloaded. If the next test happens to be one
that wants to load the module with different params, we save some
time.

If loading the module again doesn't work we should see some fireworks
in CI results elsewhere anyway. Due to module loading problems we used
to limit them to known places (reloading tests, selftests, ...) so we
might need to revisit this topic later. But no need to FUD it at this
time.
