sockets: remove ERR_CLSD case after data receive

Browse Source 
With the changes introduced in b1b6275110
it's no longer possible to get ERR_CLSD from netconn_recv_tcp_pbuf_flags
after we've received data because of the NETCONN_NOFIN flag, so remove
handling for this case. Further the NETCONN_EVT_RCVPLUS stays active in
netconn_recv_data_tcp when the NETCONN_NOFIN flag is used
