If the old kernel is working, and user update kernel then we should not request them to append "pci=realloc=off" for booting. other user that would have "pci=realloc=on" works, they could always keep that. For now, we just reduce auto enable scope, as very beginning we are doing that esp for SRIOV..., and now SRIOV would require huge range esp when num_VF could be 64. we are easy to hit the case that realloc code mess up the bios allocation when there is not above 4G 64bit mmio.
