pkt_sched: fix warning in net/sched/sch_hfsc.c

this warning:

  net/sched/sch_hfsc.c: In function ‘hfsc_enqueue’:
  net/sched/sch_hfsc.c:1577: warning: ‘err’ may be used uninitialized in this function

triggers because GCC does not recognize the (correct) error flow
between hfsc_classify(), 'cl' and 'err'.

Annotate it.
