Less NMP if the position was previously in PV.

 The intention of the patch is to avoid aggressive null move pruning (NMP) in positions that have previously been found to be important (PV nodes).
If we already do not apply NMP for current PV nodes, it makes sense to apply it less often for positions that have previously been PV nodes too.
