Laine Stump fdcd273be2 conf: return a const from virDomainNetGetActualVirtPortProfile
This also isn't required (due to the vportprofile being stored in the
NetDef as a pointer rather than being directly contained), but it
seemed dishonest to not mark it as const (and thus permit users to
modify its contents)
