arm64: kasan: Use actual memory node when populating the kernel image shadow
With the 16KB or 64KB page configurations, the generic vmemmap_populate() implementation warns on potential offnode page_structs via vmemmap_verify() because the arm64 kasan_init() passes NUMA_NO_NODE instead of the actual node for the kernel image memory.
