x86/apic: Hide unused safe_smp_processor_id() on 32-bit UP
When CONFIG_SMP is disabled in a 32-bit config, the prototype for
safe_smp_processor_id() is hidden, which causes a W=1 warning:
arch/x86/kernel/apic/ipi.c:316:5: error: no previous prototype for 'safe_smp_processor_id' [-Werror=missing-prototypes]
Since there are no callers in this configuration, just hide the definition
as well.
[ bp: Clarify it is a 32-bit config. ]
