[RESEND v4 7/7] mm, slab_common: Modify kmalloc_caches[type][idx] to kmalloc_caches[idx][type]

KMALLOC_NORMAL is the most frequently accessed, and kmalloc_caches[] is initialized by different types of the same size. So modifying kmalloc_caches[type][idx] to kmalloc_caches[idx][type] will benefit performance. $ ./scripts/bloat-o-meter vmlinux.patch_1-6 vmlinux.patch_1-7 add/remove: 0/0
