Okay, starting to understand what's the problem.

Correct and it's not optional to get the tests passing for the fc transport.

It really solves the problem that the autoconnect setup of nvme-cli is
distrubing the tests (*). The only other way I found to stop the autoconnect is
by disabling the udev rule completely. If autoconnect isn't enabled the context
isn't necessary. Though changing system configuration from blktests seems at bit
excessive.

Another option is to detect if autoconect is enabled and report this when
starting the tests. In this case we could remove the context part completely.
Obviously, I would prefer to keep it but I am certaintaly not against dropping
it and make blktests a bit simpler if this is the preference. I just need to
remember to disable the autoconnect stuff when using blktests.

(*) Sure we can fix this but at this point. Though I think it's a bit strange
for a test suite to depend/interact with external components in this way.
