tipc: reduce sensitive to retransmit failures
With huge cluster (e.g >200nodes), the amount of that flow: gap -> retransmit packet -> acked will take time in case of STATE_MSG dropped/delayed because a lot of traffic. This lead to 1.5 sec tolerance value criteria made link easy failure around 2nd, 3rd of failed retransmission attempts. Instead of re-introduced criteria of 99 faled retransmissions to fix the issue, we increase failure detection timer to ten times tolerance value.
