Currently, if qemuProcessStart fail at some point, e.g. because domain being started wants a PCI/USB device already assigned to a different domain, we jump to cleanup label where qemuProcessStop is performed. This unconditionally calls virSecurityManagerRestoreAllLabel which is wrong because the other domain is still using those devices. However, once we successfully label all devices/paths in qemuProcessStart() from that point on, we have to perform a rollback on failure - that is - we have to virSecurityManagerRestoreAllLabel.
