Small code cleanup in LMR

Browse source 
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.
