crypto: x86/serpent-sse2 - remove XTS algorithm
The XTS 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 XTS code themselves via xts_crypt(). Remove the xts-serpent-sse2 algorithm which did this. Users who request xts(serpent) and previously would have gotten xts-serpent-sse2 will now get xts(ecb-serpent-sse2) instead, which is just as fast.
