[PATCH v1 3/9] qemu: capabilities: refactor virQEMUCapsLoadHostCPUModelInfo

[Collin Walling <walling@xxxxxxxxxxxxx>]

This will be used to load the host recommended CPU model, introduced in
a subsequent patch. Also move ctxt auto restore to end of variable
declarations to avoid a compiler warning.
