From a human admin viewpoint it doesn't make sense to count the messages sent:
When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect
the MS to respond with a TMSI Realloc Complete message. When that fails to come
through, the LU actually ends in failure, even though a LU Accept was sent.
If a conn breaks/vanishes during LU, we cancel the LU without sending any reply
at all, so the failed LU would not be counted.
Instead, count Location Updating results, i.e. completion and failures.
(With the new VLR developments, LU counters need to be triggered in completely
different places, and this patch prepares for that by providing sensible
counters.)
