If the interface comes back, it will (may?) have a different device id (if-index),
even if the name is the same.

Regardless, not everyone uses SNMP, so clearing stats can still be useful.  Even
if it is not implemented perfectly (ie, no locking, so it's possible that a clear
will not totally clear some stats), it will still be right most of the time, and
that will help the casual user who is trying to diagnose network errors with only
console access to the system... (ie, ifconfig -a).
