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’
