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