liburcu doesn't have kfree_rcu (or anything similar). Despite that, we can hack around it in a trivial fashion, by adding a wrapper. This wrapper only works for maple_nodes, and not anything else (due to us not being able to know rcu_head offsets in any way), and thus we take advantage of the type checking to avoid future silent breakage.
