    qemu: domain: Don't set default USB model if qemuCaps is missing
    
    qemuDomainControllerDefPostParse assigns the default USB controller
    model when it was not specified by the user. Skip this step if @qemuCaps
    is missing so that we don't fill wrong data. This will then be fixes by
    re-running the post parse callback.
