Pan Nengyuan 77c24259b6 boot-order-test: fix memleaks in boot-order-test
It's not a big deal, but 'check qtest-ppc/ppc64' runs fail if sanitizers is enabled.
The memory leak stack is as follow:

Direct leak of 128 byte(s) in 4 object(s) allocated from:
    #0 0x7f11756f5970 in __interceptor_calloc (/lib64/libasan.so.5+0xef970)
    #1 0x7f1174f2549d in g_malloc0 (/lib64/libglib-2.0.so.0+0x5249d)
