TCP buffer处好像有一个bug

[peterguo97]

void TcpBuffer::recycleWrite(int index) {
  int j = m_write_index + index;
  //TODO: here get a bug
  if (j >= (int)m_buffer.size()) {
    ErrorLog << "recycleWrite error";
    return;
  }
  m_write_index = j;
  adjustBuffer();
}

此处是否有bug，当buffer被填满时，例如
[2022-05-18 03:04:04.214972] [DEBUG] [29062] [29064] [1] [tinyrpc/net/tcp/tcp_connection.cc:114] m_read_buffer size=128rd=0wd=0
[2022-05-18 03:04:04.214988] [DEBUG] [29062] [29064] [1] [tinyrpc/coroutine/coroutine_hook.cc:55] this is hook read
[2022-05-18 03:04:04.214998] [DEBUG] [29062] [29064] [1] [tinyrpc/net/fd_event.cc:121] fd already set o_nonblock
[2022-05-18 03:04:04.215017] [DEBUG] [29062] [29064] [1] [tinyrpc/net/tcp/tcp_connection.cc:116] read_hook func get size: 128
此时读到了128个byte，但是在调用recycleWrite时，由于0+128 >= 128而导致返回，引发后续错误
