[PATCH v2 3/5] qemu: report error if missing model name when baselining

[Collin Walling <walling@xxxxxxxxxxxxx>]

When executing the hypervisor-cpu-baseline command and the
XML file contains a CPU definition without a model name, or
an invalid CPU definition, then the commands will fail and
return an error message from the QMP response.

Let's clean this up by checking for a valid definition and
presence of a model name.

This code is copied from virCPUBaseline.
