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.

Fixes: f9040773b7bb ("arm64: move kernel image to base of vmalloc area")
