[PATCH v2] test-vmstate: Fix memleaks in test_load_qlist

[<kuhn.chenqun@huawei.com>]

From: Chen Qun <kuhn.chenqun@huawei.com>

There is memleak in test_load_qlist().It's not a big deal,
but test-vmstate will fail if sanitizers is enabled.

In addition, "ret" is written twice with the same value
 in test_gtree_load_iommu().
