It's incorrect to try to stop an expired timer:

... but that was happening with PFCP message timers. This could
possibly lead to stopping random timers that are started in the
same pfcp_process() loop iterations.
Also, print warnings when URR events are delayed by more than 5s.
This will make it possible to detect further URR timer problems
without complicated examination of PFCP PCAPs.
