ARTEMIS-2174 Broker reconnect cause OOM with scale down
When a node tries to reconnects to another node in a scale down cluster,
the reconnect request gets denied by the other node and keeps retrying,
which causes tasks in the ordered executor accumulate and eventually OOM.
The fix is to change the ActiveMQPacketHandler#handleCheckForFailover
to allow reconnect if the scale down node is the node itself.
