tools/power turbostat: fix segfault on 'no node' machines

Running turbostat on machines that don't expose nodes
in sysfs (no /sys/bus/node) causes a segfault or a -nan
value diesplayed in the log. This is caused by
physical_node_id being reported as -1 and logical_node_id
being calculated as a negative number resulting in the new
GET_THREAD/GET_CORE returning an incorrect address.
