Fix the bug which made VP8 denoiser not bit-exact between C code and SSE code.
This issue is found when the denoising mode is set to kDenoiserOnYUVAggressive. Updated the C code to make it the same with SSE version. I also changed several lines in VP9 denoiser for the code style. Change-Id: I640d48cf946fe8c6a400e6e252107501d1e226d3
