When support for hotplug/unplug of SCSI controllers was added way back in December 2009 (commit da9d937b), unplug was handled by calling the now-extinct function qemuMonitorRemovePCIDevice(), which required a PCI address as an argument. At the same time, the idea of every device in the config having a PCI address apparentlty was not yet fully

implemented, because the author of the patch including a check for a valid PCI address in the device object.
These days, all PCI devices are guaranteed to have a valid PCI address. But more important than that, we no longer detach devices by PCI address, but instead use qemuDomainDeleteDevice(), which identifies the device by its alias. So checking for a valid PCI address is just pointless extra code that obscures the high level of similarity between all the individual qemuDomainDetach*Device() functions.
