From: Eric Biggers <[email protected]>

dm-linear and dm-flakey obviously can pass through inline crypto support.

dm-zero should declare that it passes through inline crypto support, since
any reads from dm-zero should return zeroes, and blk-crypto should not
attempt to decrypt data returned from dm-zero.
