Problem: ======== - InnoDB does consecutive instant alter operation, first instant DDL fails, it fails to reset the old instant information in table during rollback. This lead to consecutive instant alter to have wrong assumption about the exisitng instant column information. Fix: ==== dict_table_t::instant_column(): Duplicate the instant information field of the table. By doing this, InnoDB alter retains the old instant information and reset it during rollback operation
