nvme: allow integrity when PI is not in first bytes
NVM command set 1.0 (or later) mandates PI to be in the last bytes of
metadata. But this was not supported in the block-layer, and driver
registered a nop profile.
Since block-integrity can now handle flexible PI offset, change the
driver to support this configuration.
