ipaidview: Fail to apply unknown (invalid) hosts

The task to apply an unknown (invalid) host to an idview was not failing
as expected and only reported no change.

A new host verification step has been added to fail before trying to
apply invalid hosts. unapplying an invalid host is not failing as the
invalid host is indeed not applied.
