Timeout, Expire stop timer if Close, Unregister fails

[Bolodya1997]

Expected Behavior

timeout, expire should not stop their internal timers and so send events if Close, Unregister events coming from the outside fail.

Current Behavior

timeout, expire chain elements stop their internal timers if Close, Unregister coming from the outside fails.

Steps to Reproduce

1. Run multiple kernel clients (50) on the NSM with replica set.
2. Kill pods for all of them at the same time to make old clients stop and new clients start.
3. There are leaked kernel interfaces even after the old clients tokens expired.
