ocfs2: Use ocfs2_extent_list instead of ocfs2_dinode.
ocfs2_extend_meta_needed(), ocfs2_calc_extend_credits() and ocfs2_reserve_new_metadata() are all useful for extent tree operations. But they are all limited to an inode btree because they use a struct ocfs2_dinode parameter. Change their parameter to struct ocfs2_extent_list (the part of an ocfs2_dinode they actually use) so that the xattr btree code can use these functions.
