block, libnvdimm, nvme: provide a built-in blk_integrity nop profile
The libnvidmm-btt and nvme drivers use blk_integrity to reserve space
for per-sector metadata, but sometimes without protection checksums.
This property is generically useful, so teach the block core to
internally specify a nop profile if one is not provided at registration
time.

[hch: kill the local nvme nop profile as well]
