How did you determine that it was still being used? When a kernel
user requests for an algorithm the system is supposed to skip
anything which failed the self-test.

CRYPTO_ALG_DEAD is used to mark algorithms deleted from the
system. However, we don't delete algorithms just because they
fail the self-test. They remain in the system so you can come
back and diagnose the problem. They just aren't used by anyone.
