perf tests stat+csv_summary: Fix unused variable references detected via shellcheck

Browse source

Running shellcheck on stat+csv_summary.sh throws below warnings:

   In tests/shell/stat+csv_summary.sh line 26:
   while read num event run pct
              ^-^ SC2034 (warning): num appears unused. Verify use (or export if used externally).
                  ^---^ SC2034 (warning): event appears unused. Verify use (or export if used externally).
                        ^-^ SC2034 (warning): run appears unused. Verify use (or export if used externally).
                            ^-^ SC2034 (warning): pct appears unused. Verify use (or export if used externally).

These variables are intentionally unused since they are needed to parse
through the output. Use "_" as a prefix for these throw away variables.
