networkxml2xmltest: Update couple of test cases

Soon, individual test cases of networkxml2xmltest will be subject
to networkValidate() call. This means, that input XMLs must be
valid (or marked as expected fail). Anyway, there are couple of
offenders:

1) 8021Qbh-net.xml setting vlan for <forward mode='private'/> is
   unsupported,
2) hostdev.xml networkValidate() will check if hostdevs specified
   for <forward mode='hostdev'/> are VFs. Use PCI addresses from
   virpcimock.
3) openvswitch-net.xml for <forward mode='bridge'/> only
   openvswitch type of virtualports is allowed.
