When a riak_kv_replrtq_snk is disabled, but riak_kv_replrtq_peer is not, then the peer will crash when it receives undefined in response to riak_kv_replrtq_snk:current_peers/1
Directly resolving this by returning an empty list has unexpected consequences. The peer may then re-add the sink queue work which could override the suspension or disabling of the snk.
