[PATCH v2 04/10] nvdimm/btt: do not call del_gendisk() if not needed

We know we don't need del_gendisk() if we haven't added
the disk, so just skip it. This should fix a bug on older
kernels, as del_gendisk() became able to deal with
disks not added only recently, after the patch titled
"block: add flag for add_disk() completion notation".
