crypto: aead - Avoid infinite loop when nivaead fails selftest
When an aead constructed through crypto_nivaead_default fails its selftest, we'll loop forever trying to construct new aead objects but failing because it already exists. The crux of the issue is that once an aead fails the selftest, we'll ignore it on the next run through crypto_aead_lookup and attempt to construct a new aead. We should instead return an error to the caller if we find an an that has failed the test. This bug hasn't manifested itself yet because we don't have any test vectors for the existing nivaead algorithms. They're tested through the underlying algorithms only.
