dm-integrity: use the nop integrity profile
Use the block layer built-in nop profile instead of duplicating it.
Tested by:
$ dd if=/dev/urandom of=key.bin bs=512 count=1
$ cryptsetup luksFormat -q --type luks2 --integrity hmac-sha256 \
--integrity-no-wipe /dev/nvme0n1 key.bin
$ cryptsetup luksOpen /dev/nvme0n1 luks-integrity --key-file key.bin
and then doing mkfs.xfs and simple I/O on the mount file system.
