rust_binder: keep NodeDeath in NodeRefInfo during process cleanup

Browse source

By keeping the NodeDeath inside the NodeRefInfo structure during process
cleanup, we avoid running its destructor under the node_refs lock. It is
still dropped shortly thereafter when the entire rbtree holding the
NodeRefInfo objects is dropped, but that occurs outside of the lock.
