Fix message timestamp on produce v3

[tulios]

Produce v3 isn't filtering undefined timestamps and is sending timestamp 0 (NaN converted) for all messages. This error should affect features that rely on the message timestamps and topics with "log.message.timestamp.difference.max.ms", the producer will throw INVALID_TIMESTAMP error.

Example on how to create a topic with the timestamp difference configuration:

await admin.createTopics({
    waitForLeaders: true,
    topics: [
      {
        topic: 'topic-with-max-timstamp-difference',
        numPartitions: 2,
        configEntries: [
          {
            name: 'message.timestamp.difference.max.ms',
            value: '604800000', // 7 days
          },
        ],
      },
    ],
  })
