The device name allocated by dev_set_name() in snic_tgt_create() needs be freed if device_add(&tgt->dev) returns error, as comment of device_add() says, it should call put_device() to drop the reference on error. Fix it by calling put_device(&rc->dev), so that the name can be freed in kobject_cleanup(). The 'tgt' is freed in snic_tgt_dev_release(), so kfree() in error path can be removed.
