crypto: skcipher - Avoid infinite loop when cipher fails selftest
When an skcipher constructed through crypto_givcipher_default fails its selftest, we'll loop forever trying to construct new skcipher objects but failing because it already exists. The crux of the issue is that once a givcipher fails the selftest, we'll ignore it on the next run through crypto_skcipher_lookup and attempt to construct a new givcipher. We should instead return an error to the caller if we find a givcipher that has failed the test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
