If there is an error during commit, we should keep the flag in order to
abort it.

It was added in 6282adbf932c ("f2fs: call set_page_dirty to attach i_wb for
cgroup ") to avoid panic in kernel with writeback supported cgroup. We
should keep it here.

How about setting atomic flag if there occurs an error during committing.
