fix bug of flip multi times

[leizhiyuan]

Ⅰ. Describe what this PR did

Ⅱ. Does this pull request fix one issue?

when occurs exceptions, if will can not read data any more, because we flip twice.

 @Test
    public void test(){
        ByteBuffer byteBuffer = ByteBuffer.allocateDirect(1024);
        byteBuffer.putInt(123);
        byteBuffer.flip();
        byteBuffer.flip();
        while (byteBuffer.hasRemaining()) {
            //
            System.out.println(byteBuffer.get());
        }
    }

Ⅲ. Why don't you add test cases (unit test/integration test)?

Ⅳ. Describe how to verify it

this test case will print nothing, only if you fix this bug

Ⅴ. Special notes for reviews
