Corrects two issues with DNS prepared query failover
...
When DNS prepared query fails over to another datacenter and the datacenter
returns some nodes, the DNS result does not translate WAN addresses even when
translation is enabled for SRV and A queries, and returns the wrong datacenter
(the one that failed over) for SRV queries.
