[libvirt] [PATCH] LXC: Fix return code evaulation in lxcCheckNetNsSupport()

[Richard Weinberger]

Commit b9dd878f (util: make it easier to grab only regular command exit)
changed the call semantics of virCommandRun() and therefore of virRun()
too. But lxcCheckNetNsSupport() was not updated.
As consequence of this lxcCheckNetNsSupport always failed and broke LXC.
