Initialize pc_tree_stats in reset_partition

Uniniatialized variables in pc_tree_stats have been set
to zero/INT64_MAX for all nodes.

If some of the partitions/sub-blocks are skipped, their
pc_tree_stats are not cleared. These stats would contain
random values, output of ml_prune_2pass_split_partition
would be different when multi-threading is enabled.

This CL fixes the issue by resetting pc_tree_stats in
reset_partition function.
