f2fs: fix the wrong stat count of calling gc
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.
