kasan: clean up is_kfence_address checks
1. Do not untag addresses that are passed to is_kfence_address: it
tolerates tagged addresses.
2. Move is_kfence_address checks from internal KASAN functions
(kasan_poison/unpoison, etc.) to external-facing ones.
Note that kasan_poison/unpoison are never called outside of KASAN/slab
code anymore; the comment is wrong, so drop it.
3. Simplify/reorganize the code around the updated checks.
