qemu: snapshot: Use better check when reverting external snapshots 

https://bugzilla.redhat.com/show_bug.cgi?id=1071264

Reverting of external snapshots is not supported currently. The check
that is present doesn't properly check for all aspects that make a
snapshot external. Use virDomainSnapshotIsExternal() to do the check.
