Subject: [PATCH net-next 11/17] tipc: Minor optimization to broadcast link synchronization logic

From: Allan Stephens <allan.stephens@...driver.com>

Optimizes processing done when contact with a neighboring node is
established to avoid recording the current state of outgoing broadcast
messages if the neighboring node isn't a valid broadcast link destination,
since this state information isn't needed for such nodes.
