    Call install_ingress_direct_goto_flows() when ovs restarts

    When ovs restarts and needs to regenerate flows, some flows will be
    missing in br-int, as follows:
     * table=60,priority=4,in_port="int-br-floating" actions=resubmit(,61)
     * table=60,priority=4,in_port="patch-tun" actions=resubmit(,61)
     * table=61,priority=0 actions=resubmit(,62)
    Call install_ingress_direct_goto_flows() again in the
    _handle_ovs_restart() to ensure generate these flows.
