Simplify seekMate score selection In #7239, we used previousScore only for pvIdx > 0, on the assumption that using it for pvIdx == 0 would be a functional change. This assumption was wrong, because for pvIdx == 0, score is always equal to previousScore. So we can remove the special case and always use previousScore. This patch is non-functional for both MultiPV 1 and MultiPV > 1. closes https://github.com/official-stockfish/Stockfish/pull/7261 No functional change
