In preparation for adding "tag only on alloc" boot time option, use KASAN_PAGE_REDZONE instead of KASAN_TAG_INVALID for poisoning the tail end of the vmalloc allocation.
Although both values are the same for hw tags, KASAN_SLAB_REDZONE is used for poisoning the tail end of a kmalloc object allocation, so maintain the pattern.
