android: binder: don't break on first dead binder_ref when releasing nodes

commit 008fa749 ("drivers: android:
binder: Move the node release code to a separate function") introduced a
bug where the refactored function binder_node_release() would
incorrectly break out of hlist_for_each_entry(). This potentially
results in not all binder nodes being released. A side effect
was observed where the Android system server did not kill all
processes when a crash is induced.
