x86: Replace cpu_2_logical_apicid[] with early percpu variable
Unlike x86_64, on x86_32, the mapping from cpu to logical apicid
may vary depending on apic in use. cpu_2_logical_apicid[] array
is used for this mapping. Replace it with early percpu variable
x86_cpu_to_logical_apicid to make it better aligned with other
mappings.
