Hmm, I see... SC2119 is false-positive for this patch, but it sometimes useful
functions which takes "$@" as arguments.

This works, but a bit ugly. Another idea is to make one of the optional
arguments mandatory, a positional argument. I think the option --device_type
worth making mandatory and explicit, like,
_nvmet_target_setup device
_nvmet_target_setup file
This will make it easier for me to review which test case uses which type.
(This might be against Sagi's comment, though.)
Daniel, what do you think?
