Fix sometimes incorrect key for prefetches STC https://tests.stockfishchess.org/tests/view/61737b4f6ce927be32558401 LLR: 2.95 (-2.94,2.94) <-2.50,0.50> Total: 138712 W: 34914 L: 34942 D: 68856 Ptnml(0-2): 421, 14817, 38894, 14817, 407 Very minor tweak since Position::key() depends on the 50 move rule counter.
