verity: remove BUG_ON alignment check

The buffer passed to the compute_hash needs to be aligned when dm-bht.c
is used in the kernel. dm-bht.c is also used by the dm-verity user-space
code where you don't need aligned buffers.

Remove the BUG_ON for now. Eventually, re-enable once we've modified
the user-space code to use aligned buffers (or once we stop use
common code).

BUG=none
TEST=Ran unittests.
