crypto: x86/twofish-3way - remove LRW algorithm

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.
