Use increased LMR horizont also in PV search

Tord says that using a lower horizon at PV nodes
looks strange and inconsistent with the general
philosophy of our search (i.e. always being more
conservative at PV nodes). So set LMR at 3 also
on search_pv().

Test result after 601 games seems to confirm this.
