rculist: avoid __rcu annotations
This avoids warnings from missing __rcu annotations
in the rculist implementation, making it possible to
use the same lists in both RCU and non-RCU cases.
We can add rculist annotations later, together with
lockdep support for rculist, which is missing as well,
but that may involve changing all the users.
