raw/ioat: fix icc build

Browse Source 
When using _mm_set_epi64() rather than _mm_set_epi64x() intrinsic, ICC
tries to use the x87 floating point registers, leading to warnings about
not properly clearing value when switching between x87 and SSE/AVX modes.

	error #13203: No EMMS instruction before call to function

Fix this by using the set64x() intrinsic.

Fixes: 0a92e63fc4cd ("raw/ioat: add local API to perform copies")
