Coverity discovered that the free(domain->os_info.fv.arch) and then usage later on during get_default_machine() and get_default_emulator() calls could result in using free()'d memory. If the 'cu_get_str_prop() failed or capsinfo == NULL, then the fv.arch wouldn't necessarily be strdup()'d. Passing a NULL os_info.fv_arch into the get*() API's is fine since they'll call findDomainInfo() which can handle a NULL arch value. Also added an initialization of val just to be safe. I don't think it's necessary though. --- NOTE: I found this during a Coverity run applying the endianness patches. For some reason Coverity "woke up" and saw this even though it hasn't found this issue in a couple months of runs since the changes to this module were made.
