0 port in wsrep_node_incoming_address

[Alex Yurchenko]

with no wsrep_node_address and wsrep_node_incoming_address set explicitly, got this:

mysql> show variables like 'wsrep%incoming%';
+-----------------------------+-----------------+
| Variable_name | Value |
+-----------------------------+-----------------+
| wsrep_node_incoming_address | 192.168.0.102:0 |
+-----------------------------+-----------------+
