crypto: serpent-sse2 - change transpose_4x4 to only use integer instructions
Matrix transpose macro in serpent-sse2 uses mix of SSE2 integer and SSE floating
point instructions, which might cause performance penality on some CPUs.
This patch replaces transpose_4x4 macro with version that uses only SSE2
integer instructions.
