libnvdimm, {btt, blk}: do integrity setup before add_disk()
commit 3ffb0ba9b567a8efb9a04ed3d1ec15ff333ada22 upstream.
Prior to 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk")
we needed to temporarily add a zero-capacity disk before registering for
blk-integrity. But adding a zero-capacity disk caused the partition
table scanning to bail early, and this resulted in partitions not coming
up after a probe of the BTT or blk namespaces.
We can now register for integrity before the disk has been added, and
this fixes the rescan problems.
Fixes: 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk")
