Fix wrong condition in PawnEntry::king_safety() Since revision 374c9e6b63d0e233371 we use also castling information to calculate king safety. So before to reuse the cached king safety score we have to veify not only king position, but also castling rights are the same of the pre-calculated ones. This is a very subtle bug, found only becuase even after previous patch, consecutives runs of 'bench' _still_ showed different numbers. Pawn tables are not cleared between 'bench' runs and in the second run a king safety score, previously evaluated under some castling rights, was reused by another position with different castling rights instead of being recalculated from scratch.
