f2fs: print type for each segment in segment_info's show



The original segment_info's show looks out-of-format:
cat /proc/fs/f2fs/loop0/segment_info
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 512
512 512 512 512 512 512 512 0 0 512
348 0 263 0 0 512 0 0 512 512
512 512 0 512 512 512 512 512 512 512
512 512 511 328 512 512 512 512 512 512
512 512 512 512 512 512 512 0 0 175

Let's fix this and show type for each segment.
cat /proc/fs/f2fs/loop0/segment_info
format: segment_type|valid_blocks
segment_type(0:HD, 1:WD, 2:CD, 3:HN, 4:WN, 5:CN)
