x86, watchdog: Compile fix when CONFIG_LOCAL_APIC not enabled

When adjusting the code to handle removing the old nmi watchdog,
I forgot to consider the compile case when the local apic is not
enabled.

This change fixes the following build error:

  arch/x86/kernel/apic/hw_nmi.c:28:6: error: redefinition of ‘touch_nmi_watchdog’
