Sliding Sync: Fix _bulk_get_max_event_pos(...) being inefficient (#17728 )

Fix `_bulk_get_max_event_pos(...)` being inefficient. It kept adding all
of the `batch_results` to the `results` over and over every time we
checked a single room in the batch.

I think we still ended up with the right answer before because we
accumulate `recheck_rooms` and actually recheck them to overwrite the
bad data we wrote to the `results` before.
