Revert "Don't split if reduced below min_split_depth"

Browse Source 
After extensive testing (I was off line this week and let
the test go on) it seems this change is useless:

After 33968 games on a QUAD (4 threads) at 15"+0.05
Mod vs Orig 5425 - 5550 - 22993 ELO -1 (+-2.1)

No functional change.
