[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.
