x86/cfi: Only define poison_cfi() if CONFIG_X86_KERNEL_IBT=y
poison_cfi() was introduced in:
9831c6253ace ("x86/cfi: Extend ENDBR sealing to kCFI")
... but it's only ever used under CONFIG_X86_KERNEL_IBT=y,
and if that option is disabled, we get:
arch/x86/kernel/alternative.c:1243:13: error: ‘poison_cfi’ defined but not used [-Werror=unused-function]
Guard the definition with CONFIG_X86_KERNEL_IBT.
