  -----------
  Do not delete any internal AVP if "C" flag is used.

When calling do_routing() with "C" flag (only check the prefix, without actually doing any routing), do not remove any AVP (in the beginning) as we do not add any (after prefix matching) -> no adding, so no deleting.
This allows you to safely call do_routing("C") while looping throuhg the GWs of another do_routing().
