dm_target_crypt - Fix compatibility with Linux
* The sector number that Linux' dm-crypt passes to its iv generators
is offset another -block_offset sectors, so that the actual sector
number is the one on the dm device, not the underlying device.
* Also fix the plain iv generator, which is supposed to be a "32-bit
little-endian version of the sector number"
* Now our dm_target_crypt can read Linux' crypt disks. This was tested
with an image using aes-cbc-essiv:sha256 and aes-cbc-plain.
