parseMessageMetadata error when broker entry metadata enable

[aloyszhang]

Describe the bug
If broker entry metadata enabled, we may get the following exception in many cases :

Received error from server: Failed to get batch size for entry java.lang.IllegalArgumentException: Invalid unknonwn tag type: 6

this problem also reported in ：
#10950
#9255
#10924

this is caused by #9046,

Before #9046 code is

public static MessageMetadata parseMessageMetadata(ByteBuf buffer) {
        try {
            // first, skip raw metadata if exist
            skipBrokerEntryMetadataIfExist(buffer);
            // initially reader-index may point to start_of_checksum : increment reader-index to start_of_metadata
            // to parse metadata
            skipChecksumIfPresent(buffer);
            int metadataSize = (int) buffer.readUnsignedInt();

            int writerIndex = buffer.writerIndex();
            buffer.writerIndex(buffer.readerIndex() + metadataSize);
            ByteBufCodedInputStream stream = ByteBufCodedInputStream.get(buffer);
            MessageMetadata.Builder messageMetadataBuilder = MessageMetadata.newBuilder();
            MessageMetadata res = messageMetadataBuilder.mergeFrom(stream, null).build();
            buffer.writerIndex(writerIndex);
            messageMetadataBuilder.recycle();
            stream.recycle();
            return res;
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

After #9046,

 public static MessageMetadata parseMessageMetadata(ByteBuf buffer) {
        MessageMetadata md = LOCAL_MESSAGE_METADATA.get();
        parseMessageMetadata(buffer, md);
        return md;
    }

    public static void parseMessageMetadata(ByteBuf buffer, MessageMetadata msgMetadata) {
        // initially reader-index may point to start_of_checksum : increment reader-index to start_of_metadata
        // to parse metadata
        skipChecksumIfPresent(buffer);
        int metadataSize = (int) buffer.readUnsignedInt();

        msgMetadata.parseFrom(buffer, metadataSize);
    }

this PR removed code

           skipBrokerEntryMetadataIfExist(buffer);

So, this may cause exceptions when parseMessageMetadata
