[SCSI] bsg: fix bsg_register_queue error path unfortunately, if IS_ERR(class_dev) is true, that means class_dev isn't null and the check in the error leg is pointless ... it's also asking for trouble to request unregistration of a device we haven't actually created (although it works currently). Fix by using explicit gotos and unregisters.
