The LRW template now wraps an ECB mode algorithm rather than the block cipher directly. Therefore it is now redundant for crypto modules to wrap their ECB code with generic LRW code themselves via lrw_crypt(). Remove the lrw-twofish-3way algorithm which did this. Users who request lrw(twofish) and previously would have gotten lrw-twofish-3way will now get lrw(ecb-twofish-3way) instead, which is just as fast.
