Upstream Bug URL:
xtrabackup --prepare will get stuck in this stack
```
#0 ib_sdi_get()
#1 dict_load_tables_from_space_id()
#2 dict_load_from_spaces_sdi ()
#3 innodb_init()
#4 xtrabackup_prepare_func()
#5 main()
```
when ib_sdi_get return DB_OUT_OF_MEMORY.
How to reproduce:
1. create table table as
CREATE TABLE `user` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `cid` int(11) NOT NULL DEFAULT '0', `uid` int(11) NOT NULL DEFAULT '0', `gold` int(11) NOT NULL DEFAULT '0', `coin` int(11) NOT NULL DEFAULT '0', `price` int(11) NOT NULL DEFAULT '0', `time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP, `type` int(11) NOT NULL DEFAULT '0', `chapterid` int(11) NOT NULL DEFAULT '0', `platformid` int(11) NOT NULL, `productlineid` int(11) NOT NULL, PRIMARY KEY (`id`,`uid`) ) ENGINE=InnoDB /*!50100 PARTITION BY HASH (`uid`) PARTITIONS 3000 */;
2. use xtrabackup 8.0 backup and prepare
