x86/entry: Fix allnoconfig build warning
The following commit: 095b7a3e7745 ("x86/entry: Convert double fault exception to IDTENTRY_DF") introduced a new build warning on 64-bit allnoconfig kernels, that have CONFIG_VMAP_STACK disabled: arch/x86/kernel/traps.c:332:16: warning: unused variable ‘address’ [-Wunused-variable] This variable is only used if CONFIG_VMAP_STACK is defined, so make it dependent on that, not CONFIG_X86_64.
