We never checked for errors on device_add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. The function xlvbd_alloc_gendisk() typically does the unwinding on error on allocating the disk and creating the tag, but since all that error handling was stuffed inside xlvbd_alloc_gendisk() we must repeat the tag free'ing as well. We set the info->rq to NULL to ensure blkif_free() doesn't crash on blk_mq_stop_hw_queues() on device_add_disk() error as the queue will be long gone by then.
