[PATCH] f2fs: change segment to section in f2fs_ioc_gc_range

[Yunlong Song]

f2fs_ioc_gc_range skips blocks_per_seg each time, however, f2fs_gc moves
blocks of section each time, so fix it from segment to section.

I'm okay with this change, BTW, I notice that I need to change it to use
sbi->blocks_per_seg * sbi->migration_granularity in my patchset if this
patch being merged firstly.

use BLKS_PER_SEC() for cleanup?
