Disable first pass partition search on speed >= 4

On speed 4 and above, use_square_only_threshold is set to BLOCK_4X4 on
non-boosted frames, so the behavior of first partition search and second
partition search are almost identical. Disabling
first_partition_search_pass thus gives significant speed up.
