[libvirt] [PATCHv3 2/2] Iface: disallow network tuning in session mode globally



Patch 43b67f2e disallowed network tuning only with qemu driver, however
this patch moved the check for root privileges into
virNetDevBandwidthSet function, so the call should now
fail in all possible cases. A mock function was created so that the test
suite doesn't fail because of unsufficient privileges.
