Fix dereference error in closure_performance.rs

- Removed unnecessary dereference operator on line 47
- The closure parameter  < /dev/null | b, &param_count| already destructures the reference
- Inside the closure, param_count is already an integer value, not a reference
- This fixes the compilation error: "type {integer} cannot be dereferenced"
