[libvirt] [PATCH] conf: fix virDomainNetGetActualDirect*() and BridgeName()

[Eric Blake]

> 
> These three functions:
> 
>   virDomainNetGetActualBridgeName
>   virDomainNetGetActualDirectDev
>   virDomainNetGetActualDirectMode
> 
> return attributes that are in a union whose contents are interpreted
> differently depending on the actual->type and so they should only
> return non-0 when actual->type is 'bridge' (in the first case) or
> 'direct' (in the other two cases, but I had neglected to do that,

> (The other two functions weren't causing any behavioral problems in
> virDomainChangeNet(), but their problem and fix was identical, so I
> included them in this same patch).
> 
> were supposed to only return non-0 values when
