Fix InstrumentedRecordInterceptor closing the trace too early

[Questlog]

The Spring Kafka InstrumentedRecordInterceptor was closing the trace before calling the decorated RecordInterceptor.

We print logs and do some other tasks inside the Kafka RecordInterceptor, especially if a failure occured after consuming an event.

This caused our logs not to be part of the trace when the kafka event got finished successfully or with failures.

@Questlog could you sign the CLA, we can not accept the PR without that.
When you call the original interceptor before ending the span you may need to consider the possibility of the original interceptor throwing an exception. Could you make the same change in https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/instrumentation/spring/spring-kafka-2.7/library/src/main/java/io/opentelemetry/instrumentation/spring/kafka/v2_7/InstrumentedBatchInterceptor.java

To sign the CLA, I have to get in contact with my companys CLA Manager to sort this out.
