Rename one variable To enhance code clarity and prevent potential confusion with the 'r' variable assigned to reduction later in the code, this pull request renames it to 'reductionScale' when we use the same name in the reduction() function. Using distinct variable names for separate functions improves code readability and maintainability. closes https://github.com/official-stockfish/Stockfish/pull/4765 No functional change
