Don't insert pv back into tt This code was added before the accurate pv patch, when we retrieved PV directly from TT. It's not required for correct (and long) PVs any more and should be safe to remove it. Also, allowing helper threads to repeatedly over-write TT doesn't seem to make sense(that was probably an un-intended side-effect of lazy smp). Before Lazy SMP only Main Thread used to run ID loop and insert PV into TT.
