FROMLIST: binder: fix death race conditions

(from https://patchwork.kernel.org/patch/9817765/)

A race existed where one thread could register
a death notification for a node, while another
thread was cleaning up that node and sending
out death notifications for its references,
causing simultaneous access to ref->death
because different locks were held.
