x86/smp: Remove the redundant #ifdef CONFIG_SMP directive
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.
