Avoid permanent PV entries in TT This patch removes a condition that allows a PV entry to remain in TT across games for an unlimited time. Although this produces a nice ELO boost in the long term it is an artifact that affects tests results bewteen version with and without this feature. So remove now and readd before to release because it actually seems a strong feature. As example a verification tournament against SF 2.0.1 starting around +10 ELO after 4K games sligltly climbed to +21 ELO after 14K games !!! Signed-off-by: Marco Costalba <mcostalba@gmail.com>
