Juergen Gross 802600ebdf x86/xen: return a sane initial apic id when running as PV guest 
With recent sanity checks for topology information added, there are now
warnings issued for APs when running as a Xen PV guest:

  [Firmware Bug]: CPU   1: APIC ID mismatch. CPUID: 0x0000 APIC: 0x0001

This is due to the initial APIC ID obtained via CPUID for PV guests is
always 0.

Avoid the warnings by synthesizing the CPUID data to contain the same
initial APIC ID as xen_pv_smp_config() is using for registering the
APIC IDs of all CPUs.

Fixes: 52128a7a21 ("86/cpu/topology: Make the APIC mismatch warnings complete")
