cc3200: Roll back to the previous telnet and ftp timeouts. 

Unfortunately, these timeouts are the only realiable way (for now), to
be able to detect broken connections due to half-open sockets. Such a
thing occurs when getting out of the WiFi coverage area or when
disconnecting from the AP (sometimes the client doesn't send the
disconnect packet).
