Can we have a little nvme_controller_mode() helper that uses
subsystem->model if it is set, and otherwise the default?  That saves
memory by not duplicating the default name for every subsystem.

I don't think we should free the old model until the new one
is allocated.

Otherwise this looks good to me, but can someone also prepare a
nvmetcli patch as well?
