[libvirt] [PATCH 7/9] conf: snapshot: check domain name on redefine

[Nikolay Shirokovskiy]

Renaming domain which has snapshots is prohibited. Also reverting
to ABI compatible active domain with a different name can have
issues later I guess. So let's prohibit changing domain name on snapshot
metadata redefine as well.
