 Description   

In MDEV-25524, the logic of rolling back RENAME operations was broken for tables that are stored in the system tablespace (created while the non-default setting innodb_file_per_table=0 was in effect). Any rename operations in the file system (dict_table_t::rename_tablespace()) are only applicable to tables that are stored in .ibd files.
