When cpu loading is high, the task maybe preempted after restoring the
sched priority in trace_android_vh_binder_free_buf(). This means that
node->has_async_transaction can't be cleared immediately and the work
isn't added to the proc->todo queue as soon as possible.
To fix this we add a new hook trace_android_vh_binder_buffer_release()
to restore the priority after node->has_async_transaction has been
updated and the node->work has been added to the proc->todo queue.
Note: the old trace_android_vh_binder_free_buf() hook is kept to avoid
breaking KMI but is not extrictly needed.
