Thanks!

(That alignment check was added after our discussion - we wanted
to have dm-crypt and dm-integrity to check the same thing, just to trigger
possible data corruption, but obviously it was incorrect check.)

It must go to stable well, I think there are possibly more situations
we broke for dm-crypt by this.
