Espressif Systems 25de141e64 fix(multi-sockets): Fix multi-clients connection abnormal ...

select() should not judge socket fd just SHUTDOWN state when other socket closed actively
those socket will be in unreadable or unwriteable

abnormal step before:[ESP8266 as the tcp server]
1. ESP8266 set up a listen port (system default: socket = 0)
2. Client 1 connect to ESP8266 OK (system default: socket = 1)
3. Client 1 send data OK
4. Client 2 connect to ESP8266 OK (system default: socket = 2)
5. Client 1 and Client 2 send data OK
6. Disconnect Client 2 actively, Client 1 send data OK
7. Client 2 reconnect to ESP8266 OK (system default: socket = 2)
8. Client 1 and Client 2 send data OK
9. Disconnect Client 1 actively, select() API will return -1
    if Client 2 send data at this time, tcp server will not work
