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

The smp_props.has_clusters in MachineClass is not a user configured
field, and it indicates if user specifies "clusters" in -smp.

After -smp parsing, other module could aware if the cluster level
is configured by user. This is used when the machine has only 1 cluster
since there's only 1 cluster by default.

Add the check to cover this field.
