After further investigation, I will not add an rte_flow_table_delete() API.
The tables are stored in an array. Deleting a table will leave an empty entry in the array.
The table_create API just adds tables to the array until the array is full, it does handle empty entries in the array. Note, the ip_pipeline code does not have a table_delete API either.
The ret_flow_classifier_free() API frees all the tables in the classifier.
