I would prefer to have prepare_scsi_debug_dev changed to drop the
devices and re-create them when invoked for the second time than to bend
the teardown mechanism for something it is not intended for. Also,
teardown/teardown_ is a poor distinction and does not say much about
intended usage. You can of course re-use parts of teardown in your
implementation, but please name the new function(s) appropriately in
that case.

Looks better indeed.
