teamd: check port link_up when a port is added with loadbalance runner
In loadbalance runner, when a port with no carrier is added, the port's
'enabled' option should have been set false, so that it can change to
other ports to send the packet.
This patch is to fix it by checking it in lb's watch_ops .port_added().
