Fix latch
Add notified_ variable to avoid wait returning before count_down has notified
other threads. The race looks something like this:
thread 1: decrement the counter outside the lock
thread 2: read counter return immediately because it's 0
thread 2: latch goes out of scope
thread 1: take lock and notify because counter is 0, but fail because latch has
gone out of scope
