[PATCH] Remove hlist_for_each_rcu() API, convert existing use to hlist_for_each_entry_rcu
Remove the hlist_for_each_rcu() API, which is used only in one place, and
is trivially converted to hlist_for_each_entry_rcu(), making the code
shorter and more readable. Any out-of-tree uses may be similarly
converted.
