x86/apic: Drop logical_smp_processor_id() inline

[ Upstream commit 8f156168 ]

The logical_smp_processor_id() inline which is only called in
setup_local_APIC() on x86_32 systems has no real value.

Drop it and directly use GET_APIC_LOGICAL_ID() at the call site and use a
more suitable variable name for readability
