Subject: [PATCH RFC 3/5] hashtable: Use the regular hlist_for_each_entry_rcu API

hlist_for_each_entry_rcu already does not do any tracing. This series
removes the notrace variant of it, so let us just use the regular API.

In a future patch, we can also remove the
hash_for_each_possible_rcu_notrace API that this patch touches.
