[bugfix] Send correct search depth in final UCI info line For quite some time SF has reported a too low final search depth in rare cases (in multi-threaded search if a non-main thread was selected). Unfortunately, the recent refactoring in #6704 means that this now happens for almost every stopped search. This PR fixes this issue, which was first spotted and reported by joergoster, by ensuring that `rootDepth` always holds the last depth for which a search was started. Fixes #6756. closes https://github.com/official-stockfish/Stockfish/pull/6761 No functional change.
