usrsock: add REMOTE_CLOSED event handler to connect

Browse source 
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.
