crypto: tcrypt - fix buffer lengths in test_aead_speed()
Fix the way the length of the buffers used for encryption / decryption are computed. For e.g. in case of encryption, input buffer does not contain an authentication tag. Signed-off-by: Robert Baronescu <robert.baronescu@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
