find/replace a few more changed variable names

fixes bug caused by f1a1f1e52f46842f4991c4d74a057fc104863d5f (WIP DHT fixup)

Sorry. I'm not really sure how this happened. It was WIP so probably I just didn't double-check my initial find/replace after yesterday's variable renaming. I didn't anticipate an impending merge.

Hopefully these were the only two but I'm literally falling asleep atm
