crypto: tcrypt - Add support for hash speed testing with keys
Currently if you speed test a hash that requires a key you'll get an error because tcrypt does not set a key by default. This patch allows a key to be set using the new module parameter klen. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
