perf tests stat+shadow_stat: Fix shellcheck warning about unused variable
Running shellcheck on stat+shadow_stat.sh generates below warning: In tests/shell/stat+shadow_stat.sh line 48: while read cpu num evt hash ipc rest ^--^ SC2034 (warning): hash appears unused. Verify use (or export if used externally). This variable is intentionally unused since it is needed to parse through the output. Use "_" as a prefix for this throw away variable.
