If a large number of namespaces is spawned on a node and TIPC is
enabled in each of these, the excessive printk tracing of network
events will cause the system to grind down to a near halt.
The traces are still of debug value, so instead of removing them
completely we fix it by changing the link state and node availability
logging debug traces.
