RDS: move more queing for loopback connections to separate queue

All instances of processing for processing of
connect/re-connect/disconnect/reject instances in RDS
should use separate workqueue dedicated for processing
for (few) local loopback connections to reduce latency
so they do not get behind processing of large number of
remote connections.  However, a few instances of such
processing do not. With this fix those are being changed
to use the workqueue dedicated for local connections.
