[PATCH blktests v3 17/20] nvme: drop default subsysnqn argument from _nvmet_passthru_target_connect

[Daniel Wagner]

Remove the last positional argument for _nvmet_passthru_target_connect
which most test pass in the default subsysnqn anyway. There is little
point in cluttering all the test textual noise.

While at it, also use subsysnqn as variable name everywhere, instead of
subsys_name.
