DefaultHttp2Connection.DefaultEndpoint#lastStreamCreated return 0 when the actual stream id is Integer.MAX_VALUE

[DreamLettuce]

Expected behavior

when stream id is Integer.MAX_VALUE, DefaultHttp2Connection.DefaultEndpoint#lastStreamCreated is expected to return Integer.MAX_VALUE

Actual behavior

1. DefaultHttp2Connection.DefaultEndpoint#lastStreamCreated return 0
2. io.netty.handler.codec.http2.StreamBufferingEncoder#isExistingStream return false
3. StreamBufferingEncoder write data frame failed

4. the further problem is that grpc-java does not handle this write data failure in NettyClientStream
   .this result to the grpc client thread hangs forever is we use grpc blocking stub

Steps to reproduce

add the following test case to io.netty.handler.codec.http2.StreamBufferingEncoderTest

    @Test
    public void testExhaustedStreamId() throws Http2Exception {
        int nextStreamId = Integer.MAX_VALUE - 2;
        testStreamId(nextStreamId);
        nextStreamId = connection.local().incrementAndGetNextStreamId();
        testStreamId(nextStreamId);
    }

    private void testStreamId(int nextStreamId) throws Http2Exception {
        connection.local().createStream(nextStreamId, false);
        ByteBuf data = data();
        ChannelFuture channelFuture = encoder.writeData(ctx, nextStreamId, data, 0, false, newPromise());
        if (channelFuture.cause() != null) {
            channelFuture.cause().printStackTrace();
        }
        assertTrue(channelFuture.cause() == null);
    }
