kasan, x86, s390: update undef CONFIG_KASAN
With the intoduction of hardware tag-based KASAN some kernel checks of
this kind:
ifdef CONFIG_KASAN
will be updated to:
if defined(CONFIG_KASAN_GENERIC) || defined(CONFIG_KASAN_SW_TAGS)
x86 and s390 use a trick to #undef CONFIG_KASAN for some of the code
that isn't linked with KASAN runtime and shouldn't have any KASAN
annotations.
Also #undef CONFIG_KASAN_GENERIC with CONFIG_KASAN.
