crypto: testmgr - check skcipher min_keysize
When checking two implementations of the same skcipher algorithm for consistency, require that the minimum key size be the same, not just the maximum key size. There's no good reason to allow different minimum key sizes. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
