X-link: https://github.com/facebookresearch/FBGEMM/pull/2064

We observe, if the memory of output is uninitialized, the output may be garbage.

This is because certain memory is untouched. The proposed fix is a quick workaround, but it will be more efficient to directly fill the untouched memory with zero.
