Remove old line in "Futility pruning for captures" The line is no longer needed after https://github.com/official-stockfish/Stockfish/commit/910cf8b21839eb9f1991934a5436eea112021723. This patch incidentally applies "Futility Pruning for Captures" also in case of en-passant, changing the bench signature.
