f2fs: retrieve IO write stat from the right place

Browse Source 
In the following patch,

    f2fs: split journal cache from curseg cache

journal cache is split from curseg cache. So IO write statistics should be
retrived from journal cache but not curseg->sum_blk. Otherwise, it will
get 0, and the stat is lost.
