testing/radix-tree/maple: Hack around kfree_rcu not existing
liburcu doesn't have kfree_rcu (or anything similar). Despite that, we
can hack around it in a trivial fashion, by adding a wrapper.
The wrapper only works for maple_nodes because we cannot get the
kmem_cache pointer any other way in the test code.
