crypto: x86/camellia - remove LRW algorithm

Browse Source 
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-camellia-asm algorithm which did this.  Users who request
lrw(camellia) and previously would have gotten lrw-camellia-asm will now
get lrw(ecb-camellia-asm) instead, which is just as fast.
