crypto: skcipher - Realign struct skcipher_walk to save 8 bytes 



Reduce skcipher_walk's struct size by 8 bytes by realigning its members.

pahole output before:

  /* size: 120, cachelines: 2, members: 13 */
  /* sum members: 108, holes: 2, sum holes: 8 */
  /* padding: 4 */
  /* last cacheline: 56 bytes */

and after:

  /* size: 112, cachelines: 2, members: 13 */
  /* padding: 4 */
  /* last cacheline: 48 bytes */

No functional changes intended.
