ruby: mesi coherence protocol: invalidate lock
The MESI CMP directory coherence protocol, while transitioning from SM to IM,
did not invalidate the lock that it might have taken on a cache line. This
patch adds an action for doing so.
The problem was found by Dibakar, but I was not happy with his proposed
solution. So I implemented a different solution.
