x86/entry: Fix allnoconfig build warning

Browse source

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.
