ANDROID: binder: correctly initialize ref to zombie node.

Browse Source 
When we create a new reference to a zombie node
(which is allowed as long as there are other refs
to the node), we don't correctly initialize the
node_is_zombie field of the ref, which can lead to
death recipients never being fired.
