tipc: simplify link timer handling
Prior to this commit, the link timer has been running at a "continuity interval" of configured link tolerance/4. When a timer wakes up and discovers that there has been no sign of life from the peer during the previous interval, it divides its own timer interval by another factor four, and starts sending one probe per new interval. When the configured link tolerance time has passed without answer, i.e. after 16 unacked probes, the link is declared faulty and reset. This is unnecessary complex. It is sufficient to continue with the original continuity interval, and instead reset the link after four missed probe responses. This makes the timer handling in the link simpler, and opens up for some planned later changes in this area. This commit implements this change.
