Daniel Jurgens 805b754d49 IB/core: Eliminate a hole in MAD agent struct

Move the security related fields above the u8s to eliminate a hole in the
struct.

pahole before:
struct ib_mad_agent {
...
u32                        hi_tid;               /*    48     4 */
u32                        flags;                /*    52     4 */
u8                         port_num;             /*    56     1 */
u8                         rmpp_version;         /*    57     1 */

/* XXX 6 bytes hole, try to pack */

/* --- cacheline 1 boundary (64 bytes) --- */
void *                     security;             /*    64     8 */
bool                       smp_allowed;          /*    72     1 */
bool                       lsm_nb_reg;           /*    73     1 */

/* XXX 6 bytes hole, try to pack */

struct notifier_block      lsm_nb;               /*    80    24 */

/* XXX last struct has 4 bytes of padding */

/* size: 104, cachelines: 2, members: 14 */
...
};

pahole after:
struct ib_mad_agent {
...
u32                        hi_tid;               /*    48     4 */

u8                         port_num;             /*    88     1 */
u8                         rmpp_version;         /*    89     1 */
bool                       smp_allowed;          /*    90     1 */
