sgsn: Remove the "permanent" subscriber cache

The subscriber cache would help in case:

  * GPRS DETACH, GPRS ATTACH. In that case we might still
  have some cached authentication tuples we avoid another
  sendAuthenticationInfo request.

  * After a detach the cache expiry would make sure to
  eventually send a purgeMS to the HLR (which might be
  ignored).

At the same time to make the cache work we will need to
make sure to start and stop timers. In case we don't
start we might accumulate subscribers. I am afraid that
the above two benefits do not outweight the complexity
of this implementation.
