Fix bug in using first pass stats in second pass

active_h_edge() and active_v_edge() use first pass stats to decide whether
or not this block is within the inactive region. There are bugs in the code.

1. frame_stats_arr stats buffer is only used in the first pass, and is invalid
in the second pass. Should get stats from twopass->stats_in.
2. mi size is 4x4 in AV1, need to modify the code accordingly.

Ran AWCY tests before/after the CL. Saw no quality difference except 1 clip:
kirland360p_60f.y4m, which got a small gain.
