Commit "rhashtable: Introduce rhashtable_walk_*" forgot to initialize the
members of struct rhashtable_walker after allocating it, which caused
an undefined value for 'resize' which is used later on.

The change seems fine to me, although the INIT_LIST_HEAD() unnecessary
due to the below list_add()?
Anyway, setting resize to false is definitely correct. In practice this
shouldn't cause much issue though as rhashtable_walk_start() would only
reset iterator meta data and set resize to false, but lets fix it.
mutex_lock(&ht->mutex);
list_add(&iter->walker->list, &ht->walkers);
mutex_unlock(&ht->mutex);
Thanks,
Daniel
