Now f2fs will check statistics recorded in super block in
sanity_check_area_boundary() during mount,if number of segments per
section is greater than 1, and the disk space isn't aligned with section,
mount will fail due to following condition:
main_blkaddr + (segment_count_main << log_blocks_per_seg) !=
segment0_blkaddr + (segment_count << log_blocks_per_seg)
this is because when the length of main area isn't aligned with section,
mkfs didn't add the number of excess segments to segment_count_main, but
add it to segment_count.
Here align segment_count with section size first to prevent such problem.
