[CRYPTO] blkcipher: Remove alignment restriction on block size
Previously we assumed for convenience that the block size is a multiple of
the algorithm's required alignment. With the pending addition of CTR this
will no longer be the case as the block size will be 1 due to it being a
stream cipher. However, the alignment requirement will be that of the
underlying implementation which will most likely be greater than 1.
