    XenAPI: Don't use nicira-iface-id for XenServer VIF
    
    When using neutron polling mode, booting a VM will timeout because
    nova-compute cannot receive network-vif-plugged event. This is
    because we set vif['id'](i.e. neutron port uuid) to two different
    OVS ports. One is Xenserver VIF, the other is tap device qvo-XXXX
    which neutron ovs agent will monitor and deal with.
    My previous patch https://review.openstack.org/#/c/463246/ has
    deprecated the setting of 'nicira-iface-id' to XenServer. This
    patch is to remove the setting of 'nicira-iface-id'.

  Fix Released

Bug description:
  Precondition:
  1. XenAPI driver in nova with XenServer 7.1
  2. minimize_polling = True in neutron-openvswitch-agent running for dom0 (q-domua in devstack)
