Retire broken SendSearchedNodes

Now that we can split at root it happens that SendSearchedNodes
works only once at the end of the iteration, but this is useless
becuase speed info is sent anyhow toghter with the pv line.

So retire for now, waiting to find something SMP compatible.

No functional change.
