[PATCH v2 1/3] hw/smbios: Fix smbios_smp_sockets caculation

[Zhao Liu]

From: Zhao Liu <zhao1.liu@intel.com>

Here're 2 mistakes:
1. 003f230e37d7 ("machine: Tweak the order of topology members in struct
   CpuTopology") changes the meaning of smp.cores but doesn't fix
   original smp.cores uses. And because of the introduction of cluster,
   now smp.cores means the number of cores in one cluster. So smp.cores
   * smp.threads just means the cpus in a cluster not in a socket.
2. smp.cpus means the number of initial online cpus, not the total
   number of cpus. For such topology calculation, smp.max_cpus
   should be considered.

Since the number of sockets has already been recorded in smp structure,
use smp.sockets directly.

Fixes: 003f230e37d7 ("machine: Tweak the order of topology members in struct 
CpuTopology")
