pf_ul(): report if UEs scheduled

Browse Source 
For the multi-UL slot scheduling functionality in a follow-up commit, it
would be important to know if the scheduler allocated any UEs. If
pf_ul() allocated for some UEs, we might run it again on a different
slot. If on the other hand, no UEs were allocated, there is no point in
running it again.
