Subject: [PATCH v2] tipc: initialise addr_trail_end when setting node addresses

Ensure addr_trail_end is set to jiffies when configuring the node
address. This ensures that we don't treat the initial value of 0 as
being a wrapped. This isn't a problem when using auto-generated node
addresses because the addr_trail_end is updated for the duplicate
address detection phase.
