linux-gen: sched: next spread after no input packets
When packet input poll does not return packets, move to the
next spread instead of the next group/priority. Since packet
input queues are not removed from scheduling when they are
empty, this branch may be taken often. Scheduling is more
fair (to other queues in the same group/priority) when the
remaining spreads are not skipped.
