[PATCH] qemu_namespace: Don't build namespace if domain doesn't have it enabled

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Even if namespaces are disabled, then due to a missing check at the
beginning of qemuDomainBuildNamespace(), the domain startup code
still tries to populate (nonexistent) domain's namespace.

Fixes: 8da362fe62766b4eee209cd3ce591ceb62299d13
