With a partition which was formated as multi segments in one section, we stated incorrectly for count of gc operation.
e.g., for a partition with segs_per_sec = 4 cat /sys/kernel/debug/f2fs/status GC calls: 208 (BG: 7) - data segments : 104 (52) - node segments : 104 (24) GC called count should be (104 (data segs) + 104 (node segs)) / 4 = 52, rather than 208. Fix it.
