[PATCH] events: Don't fail on registering events for two different domains

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

virConnectDomainEventRegisterAny() takes a domain as an argument.
So it should be possible to register the same event (be it
VIR_DOMAIN_EVENT_ID_LIFECYCLE for example) for two different domains.
That is, we need to take domain into account when searching for
duplicate event being already registered.
