If something goes wrong in testDomainGetDiskErrors() then we try
to free any strings that were previously allocated in return
array. Problem is, in my review of original patch (89320788ac4)
I've mistakenly did some changes which result in possible NULL
dereference (@vm is set to NULL as the first thing under cleanup
label).
