MDEV-25295 Aborted FTS_DOC_ID_INDEX considered as existing FTS_DOC_ID_INDEX during DDL

Browse Source 
InnoDB should skip the dropped aborted FTS_DOC_ID_INDEX while
checking the existing FTS_DOC_ID_INDEX in the table. InnoDB
should able to create new FTS_DOC_ID_INDEX if the fulltext
index is being added for the first time.
