Alexey Dobriyan fe08a9d498 reiserfs: shrink superblock if no xattrs 
This makes in-core superblock fit into one cacheline here.

Before:
    struct dentry *            xattr_root;           /*   124     4 */
    /* --- cacheline 1 boundary (128 bytes) --- */
    struct rw_semaphore        xattr_dir_sem;        /*   128    12 */
    int                        j_errno;              /*   140     4 */
    }; /* size: 144, cachelines: 2 */
       /* sum members: 142, holes: 1, sum holes: 2 */
       /* last cacheline: 16 bytes */

After:
    int                        j_errno;              /*   124     4 */
    /* --- cacheline 1 boundary (128 bytes) --- */
    }; /* size: 128, cachelines: 1 */
       /* sum members: 126, holes: 1, sum holes: 2 */
