Ok, I already had a similar check, but it was
in crypto_ctr_init_tfm(). I don't think that was
best place to have it.
I have moved this check to crypto_ctr_alloc().

Ok, I think I understand.
blocksize of aes is still 16, but of ctr(aes,X,Y) is 1...
Thus my instance of ctr(aes,X,Y) should have a
blocksize of 1, right? I have changed,
inst->alg.cra_blocksize = alg->cra_blocksize;
to
inst->alg.cra_blocksize = 1;
So, the correct way to say it is that my plaintext should be
multiple of cipher's blocksize, not CTR's blocksize?

Ok. I should have thought of that! :-)
I have made suggested changes in new patch below.
This time, all the ctr testcases passed. :-)
Thanks!
