Silence security alert warning about possible infinite loop As some have noticed, a security alert has been complaining about a for loop in our TB code for quite some now. Though it was never a real issue, so not of high importance. A few lines earlier the symlen vector is resized `d->symlen.resize(number<uint16_t, LittleEndian>(data));` while this code seems odd at first, it resizes the array to at most (2 << 16) - 1 elements, basically making the infinite loop issue impossible to occur. closes https://github.com/official-stockfish/Stockfish/pull/4953 No functional change
