perf tests stat+shadow_stat: Fix shellcheck warning about unused variable

Browse source

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.
