[PATCH 4.19 81/85] tipc: initialise addr_trail_end when setting node addresses

[ Upstream commit 8874ecae2977e5a2d4f0ba301364435b81c05938 ]

We set the field 'addr_trial_end' to 'jiffies', instead of the current
value 0, at the moment the node address is initialized. This guarantees
we don't inadvertently enter an address trial period when the node
address is explicitly set by the user.
