Simplify KBNK endgame implementation We do not need to change the winnerKSq variable, so we can simplify a little bit the logic of the code by changing only the loserKSq variable when it is necessary. Also consolidate and clarify comments. See the pull request thread for a proof that the code is correct: https://github.com/official-stockfish/Stockfish/pull/1854 No functional change
