Fix a bug introduced by c1ec02be1d79. It may happen that the executor opens indexes on the result relation, but no rows end up being inserted. Then the index_insert_cleanup still gets executed, but passes down NULL to the AM callback. The AM callback may not expect this, as is the case of brininsertcleanup, leading to a crash. Fixed by only calling the cleanup callback if (ii_AmCache != NULL). This way the AM can simply assume to only see a valid cache.
