ocfs2: Set journal descriptor to NULL after journal shutdown
Patch sets journal descriptor to NULL after the journal is shutdown. This ensures that jbd2_journal_release_jbd_inode(), which removes the jbd2 inode from txn lists, can be called safely from ocfs2_clear_inode() even after the journal has been shutdown.
