Please test attached patch.
If I understood ltulip correctly, it is posible, that number of entries
can be higher than requested budget. When work_done is equal to
budget-1, the last skb has to be processed, after 154'th line
work_done will become equal to budget and thus loop has to break,
check on the same 154 line will become false, but work_done will be
increased nevertheless, which will make work_done being equal to
budget+1 at exit, which will fire warning you saw.
