Ben Walker 7b0579df17 nvme: Use a non-temporal move instruction when copying NVMe cmd
When copying the NVMe command from the request to the actual
submission queue slot, use a non-temporal move instruction.

The submission queue slots are never read by software - only
written to. So don't pollute the CPU cache with their contents.
