[PATCH] Fix memory leak in testDomainCreateXMLMixed()

[Nehal J Wani <nehaljw.kkd1@xxxxxxxxx>]

While running objecteventtest, it was found that valgrind pointed out the
following memory leak:

==13025== 538 (56 direct, 482 indirect) bytes in 1 blocks are definitely lost in loss record 216 of 226
==13025==    at 0x4A06B6F: calloc (vg_replace_malloc.c:593)
    ==13025==    by 0x4C65D8D: virAllocVar (viralloc.c:558)
