The third test vector of ECB-XTEA-ENC fails for me all other
are fine. I could not find a RFC or something else where they
are defined. The test vector has not been modified since git
started recording histrory. The implementation is very close
(not to say equal) to what is available as Public Domain (they
recommend 64 rounds and the in kernel uses 32). Therefore I
belive that there is typo somewhere and tcrypt reported always
*fail* instead of *okey*.
This patch replaces input + result of the third test vector with
result + input from the third decryption vector. The key is the
same, the other three test vectors are also the reverse.
