Subject: [PATCH] [rx-ra-tracker] use `mIsRunning` in stale timer callback
 (#12076)

`RxRaTracker` can run independently of `RoutingManager`. Its stale timer
callback should check its own running state (`mIsRunning`) instead of
`RoutingManager`'s state.

This commit corrects the logic in `HandleStaleTimer()` to use the local
`mIsRunning` flag.
