In RENAME TABLE, when an error occurs while renaming FOREIGN KEY constraint, that error would be overwritten when renaming the InnoDB internal tables related to FULLTEXT INDEX. row_rename_table_for_mysql(): Do not attempt to rename the internal tables if an error already occurred. This problem was originally reported as Oracle Bug#27545888.
