ocfs2: Store the ocfs2_caching_info on ocfs2_extent_tree.
What do we cache? Metadata blocks. What are most of our non-inode metadata
blocks? Extent blocks for our btrees. struct ocfs2_extent_tree is the
main structure for managing those. So let's store the associated
ocfs2_caching_info there.
This means that ocfs2_et_root_journal_access() doesn't need struct inode
anymore, and any place that has an et can refer to et->et_ci instead of
INODE_CACHE(inode).
