dm crypt: fix large block integrity support

Browse source

Previously, dm-crypt could use blocks composed of multiple 512b sectors
but it created integrity profile for each 512b sector (it padded it with
zeroes).  Fix dm-crypt so that the integrity profile is sent for each
block not each sector.

The user must use the same block size in the DM crypt and integrity
targets.
