net: fix up a few missing hashtable.h conflict resolutions

There are a couple of leftover symbol conflicts caused by hashtable.h
being included by netdevice.h; those were not caught as build failure
(they're "only" a warning, but in fact real bugs). Fix those up.

Fixes: e87a8f24c ("net: resolve symbol conflicts with generic hashtable.h")
