hw/smbios: Fix core count in type4
>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 003f230e37d7 ("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 003f230e37d7 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.
