This error is intentional.  This is so that you can test again
without having to unload the module.

It doesn't have to do anything.  As long as it causes the algorithm
to be registered the crypto API will test it automatically.  So
after doing the modprobe, can you find the algorithm in /proc/crypto
and if so what does its test status say?
