[ovs-dev] [PATCH v2] netdev-dpdk: update vhost user client port status.

[wangzhike]

After ovs-vswitchd reboots, vhost user client port status is displayed as
LINK DOWN though the traffic is OK.

The problem is that the port may be udpated while the vhost_reconfigured
is false. Then the vhost_reconfigured is updated to true. As a result,
the vhost port status is kept as LINK-DOWN.
