tools/power/x86/intel-speed-select: Fix display for unsupported levels

During call to "intel-speed-select turbo-freq info" some junk values are
reported for unsupported levels. Initialize the structure fact_info with
0s, so that isst_fact_display_information() will skip "0" values in the
frequency.
