Details:

disconnecting a connected UDP socket by calling connect() with parameter
name->sin_family = AF_UNSPEC allways reports an EIO error (illegal argument).

in function lwip_connect, if parameter name->sin_family = AF_UNSPEC,
netconn_disconnect() should be called, but before that, the parameter is
checked and an error is returned if name->sin_family is not equal to AF_INET.
