>From SMBIOS 3.0 specification, core count field means:

Core Count is the number of cores detected by the BIOS for this
processor socket. [1]

Before 003f230e ("machine: Tweak the order of topology members in
struct CpuTopology"), MachineState.smp.cores means "the number of cores
in one package", and it's correct to use smp.cores for core count.

But 003f230e changes the smp.cores' meaning to "the number of cores
in one die" and doesn't change the original smp.cores' use in smbios as
well, which makes core count in type4 go wrong.

Fix this issue with the correct "cores per socket" caculation.
