crypto: aead - Fix corner case in crypto_lookup_aead
When the user explicitly states that they don't care whether the algorithm has been tested (type = CRYPTO_ALG_TESTED and mask = 0), there is a corner case where we may erroneously return ENOENT. This patch fixes it by correcting the logic in the test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
