[ Upstream commit 78efac537de33faab9a4302cc05a70bb4a8b3b63 ]
Now, we have supported cgroup writeback, it depends on correctly IO account of specified filesystem.
But in commit d1b3e72d5490 ("f2fs: submit bio of in-place-update pages"), we split write paths from f2fs_submit_page_mbio() to two: - f2fs_submit_page_bio() for IPU path - f2fs_submit_page_bio() for OPU path
But still we account write IO only in f2fs_submit_page_mbio(), result in incorrect IO account, fix it by adding missing IO account in IPU path.
