x86/smp: Remove the redundant #ifdef CONFIG_SMP directive

Browse source 
The !CONFIG_X86_LOCAL_APIC section in smp.h wraps the define of
hard_smp_processor_id() into #ifndef CONFIG_SMP. But Kconfig has:

  config X86_LOCAL_APIC
    def_bool y
    depends on X86_64 || SMP || X86_32_NON_STANDARD ...

Therefore SMP can't be 'y' when X86_LOCAL_APIC == 'n'.

Remove the redundant #ifndef CONFIG_SMP.
