x86/mce: Avoid unnecessary padding in struct mce_bank

Browse source

Convert struct mce_bank member "init" from bool to a bitfield to get rid
of unnecessary padding.

$ pahole -C mce_bank arch/x86/kernel/cpu/mce/core.o

before:

  /* size: 16, cachelines: 1, members: 2 */
  /* padding: 7 */
  /* last cacheline: 16 bytes */

after:

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

No functional changes.
