conf: Revert some code to resolve issues for hostdev hotplug This patch reverts parts of commits 0d8b24f6b and 0785966d dealing with the addition of a controller during virDomainHostdevAssignAddress. This caused a regression for the hostdev hotplug path which assumes the qemuDomainFindOrCreateSCSIDiskController will add the new controller during qemuDomainAttachHostSCSIDevice to both the running domain and the domain def controller list when the controller doesn't yet exist (whether due to no SCSI controllers existing or the addition of a new controller because existing ones are full). Since commit id 0d8b24f6 will call virDomainHostdevAssignAddress during virDomainDeviceDefPostParseInternal which is called either during domain definition post processing (via an iterator during virDomainDefPostParse) or directly from virDomainDeviceDefParse during hotplug, the change broke the "side effect" of being able to add both a hostdev and controller to the running domain. The regression would only be seen if the running domain didn't have a SCSI controller alrady defined or if the existing SCSI controller was
typo already
"full" of devices and a new controller needed to be created. This patch will also add some extra comments to the code to avoid a similar future change.
