Rather than one function serving two purposes, let's split things up into qemuDomainResetSCSIControllerModel for all current callers and then add qemuDomainCheckSCSIControllerModel when building the controller command line to check the capabilities.

Or, just have this function take virDomainControllerModelSCSI enum and instead of default have VIR_DOMAIN_CONTROLLER_MODEL_SCSI_LAST and probably VIR_DOMAIN_CONTROLLER_MODEL_SCSI_AUTO; That way, when new model is added compiler identifies this place for adjustment automatically.
