[PATCH v2 01/13] nvdimm/btt: do not call del_gendisk() if not needed

[Luis Chamberlain]

del_gendisk() is not required if the disk has not been added.
On kernels prior to commit 40b3a52ffc5bc3 ("block: add a sanity
check for a live disk in del_gendisk") it is mandatory to not
call del_gendisk() if the underlying device has not been through
device_add().

Fixes: 41cd8b70c37a ("libnvdimm, btt: add support for blk integrity")
