[libvirt] [PATCH 1/4] src: Check for virDomainDiskInsert() retval properly

Our coding style specifies that only negative values are considered as error. Check for return value of virDomainDiskInsert() properly, following the style. Not that the function can now return anything other than 0 or -1, but it just triggers my OCD.
