crypto: engine - Realign struct crypto_engine to save 8 bytes
Realign struct crypto_engine to reduce its size by 8 bytes. Total size
is now 192 bytes, allowing it to fit within 3 cachelines instead of 4.
pahole output before:
/* size: 200, cachelines: 4, members: 17 */
/* sum members: 183, holes: 3, sum holes: 17 */
/* paddings: 1, sum paddings: 4 */
/* last cacheline: 8 bytes */
and after:
/* size: 192, cachelines: 3, members: 17 */
/* sum members: 183, holes: 2, sum holes: 9 */
/* paddings: 1, sum paddings: 4 */
No functional changes intended.
