实在太难受了at_resp_parse_line_args_by_kw多一个\r

这家伙很懒，什么也没写！

这并不是多出来一个 ‘\r’，而是，AT 组件在进行数据接收时，将每一行的最后一个字符，一般是 ‘\n’重写成了’\0’；

/* current receive is response */
client->recv_line_buf[client->recv_line_len - 1] = '\0';
if (resp->buf_len + client->recv_line_len < resp->buf_size)
{
    /* copy response lines, separated by '\0' */
    rt_memcpy(resp->buf + resp->buf_len, client->recv_line_buf, client->recv_line_len);
    /* update the current response information */
    resp->buf_len += client->recv_line_len;
    resp->line_counts++;
}
else
{
    client->resp_status = AT_RESP_BUFF_FULL;
    LOG_E("Read response buffer failed. The Response buffer size is out of buffer size(%d)!", resp->buf_size);
}
