[PATCH 3/4] ocfs2: stop using bdev->bd_super for journal error logging

[Christoph Hellwig <hch@lst.de>]

All ocfs2 journal error handling and logging is based on buffer_heads,
and the owning inode and thus super_block can be retrieved through
bh->b_assoc_map->host.  Switch to using that to remove the last users
of bdev->bd_super.
