    usrsock: add REMOTE_CLOSED event handler to connect
    
    when usrsock client try to connect usrsock server local_loop
    socket with an invalid port, server cannot find a listener conn
    to handle this connet request, then it will response a TCP_RESET
    packet via nuttx existing processing, when before conn recv this
    RESET packet, it will trigger usrsock_rpmsg_server poll return
    and send REMOTE_CLOSE event to usrsock client.
    so usrsock connect_event fucntion need handle this event.
