ocfs2: clear journal dirty flag after shutdown journal
Dirty flag of the journal should be cleared at the last stage of umount, if do it before jbd2_journal_destroy(), then some metadata in uncommitted transaction could be lost due to io error, but as dirty flag of journal was already cleared, we can't find that until run a full fsck. This may cause system panic or other corruption.
