[libvirt] [PATCH 1/9] virNetDevParseMcast: Avoid magic constant

[Michal Privoznik]

There is no guarantee that an enum start it mapped onto a value
of zero. However, we are guaranteed that enum items are
consecutive integers. Moreover, it's a pity to define an enum to
avoid using magical constants but then using them anyway.
