Functions that create a device node after domain startup (used from hotplug) will get a list of paths they want to create and eventually call qemuDomainNamespaceMknodPaths() which then checks whether domain mount namespace is enabled in the first place. Alternatively, on device hotunplug, we might want to delete a path inside domain namespace in which case qemuDomainNamespaceUnlinkPaths() checks whether the namespace is enabled. While this is not dangerous, it certainly burns a couple of CPU cycles needlessly. Check whether mount namespace is enabled upfront.
