sch_api: Change signature of qdisc_tree_reduce_backlog() to use ints
There are now several places where qdisc_tree_reduce_backlog() is called with a negative number of packets (to signal an increase in number of packets in the queue). Rather than rely on overflow behaviour, change the function signature to use signed integers to communicate this usage to people reading the code.
