x86: Suppress KMSAN reports in arch_within_stack_frames()
arch_within_stack_frames() performs stack walking and may confuse
KMSAN by stepping on stale shadow values. To prevent false positive
reports, disable KMSAN checks in this function.
This fixes KMSAN's interoperability with CONFIG_HARDENED_USERCOPY.
