row_undo_mod_clust_low(): If we are in recovery and rolling back a DELETE operation on the SYS_INDEXES table, and the SYS_INDEXES.NAME starts with the magic byte 0xff that identifies uncommitted ADD INDEX stubs, we must not try to evict the table definition because such index stubs would be skipped by dict_load_indexes() anyway.
