swoole_client bug

```php
<?php
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); //0m~B步m~]~^m~X[0m~^

$client->on("connect", function($cli) {
    $cli->send("hello world\n");
});

$client->on("receive", function($cli, $data = ""){
    $data = $cli->recv(); //1.6.10+ 0m~Mm~\~@0m~A
    if(empty($data)){
        $cli->close();
        echo "closed\n";
    } else {
        echo "received: $data\n";
        sleep(1);
        $cli->send("hello\n");
    }
});

$client->on("close", function($cli){
    $cli->close(); // 1.6.10+ 0m~Mm~\~@0m~A
    echo "close\n";
});

$client->on("error", function($cli){
    exit("error\n");
});

$client->connect('127.0.0.1', 9501, 0.5);
```

strace 结果
```
close(0)                                = -1 EBADF (Bad file descriptor)
close(0)                                = -1 EBADF (Bad file descriptor)
close(0)                                = -1 EBADF (Bad file descriptor)
close(0)                                = -1 EBADF (Bad file descriptor)
close(0)                                = -1 EBADF (Bad file descriptor)
close(0)                                = -1 EBADF (Bad file descriptor)
