x86/mce: Sort mca_config members to get rid of unnecessary padding

Browse Source 
$ pahole -C mca_config arch/x86/kernel/cpu/mce/core.o

before:

   /* size: 40, cachelines: 1, members: 16 */
   /* sum members: 21, holes: 1, sum holes: 3 */
   /* sum bitfield members: 64 bits, bit holes: 2, sum bit holes: 32 bits */
   /* padding: 4 */
   /* last cacheline: 40 bytes */

after:

   /* size: 32, cachelines: 1, members: 16 */
   /* padding: 3 */
   /* last cacheline: 32 bytes */

No functional changes.
