    catch libvirt exception when nodedev not found.

    This is a minimal fix to workaround instance where libvirt
    retruns stale data due to internal caching. In some cases
    libivrt can return stale data vai the nodedev api when the
    mac adress of an interface such as an sriov virtual function
    canages, i.e. when a mac adress is reset after a vm with
    a virtual funciton is migrated.
