Michal Privoznik 4f819d9457 testCompareMemLock: Use correct free function for domain def
virDomainDef is not an instance of virObject thus
virObjectUnref() is not the correct function to be called.

/* The tests below make sure that the memory locking limit is being

*
* kvm: simple KMV guest
* tcg: simple TCG guest
*
* hardlimit: guest where <memtune><hard_limit> has been configured
* locked: guest where <memoryBacking><locked> has been enabled
* hostdev: guest that has some hostdev assigned
*
* The remaining tests cover different combinations of the above to
* ensure settings are prioritized as expected.
