By moving some fields around, this patch shrinks
holes size from 56 to 32, saving 24 bytes on 64bit arches.
After the patch pahole gives the following for 'struct tcp_sock':
/* size: 2304, cachelines: 36, members: 162 */
/* sum members: 2234, holes: 6, sum holes: 32 */
/* sum bitfield members: 34 bits, bit holes: 5, sum bit holes: 14 bits */
/* padding: 32 */
/* paddings: 3, sum paddings: 10 */
/* forced alignments: 1, forced holes: 1, sum forced holes: 12 */
