Small code cleanup in LMR In a recent patch we added comparing capture history to a number for LMR of captures. Calling it via thisThread-> is not needed since capture history was already declared by this time - so removing makes code slightly shorter and easier to follow. closes https://github.com/official-stockfish/Stockfish/pull/3297 No functional change.
