pkt_sched: Fix warning false positives.

GCC refuses to recognize that all error control flows do in fact set err to something. Add an explicit initialization to shut it up. net/sched/sch_drr.c: In function ‘drr_enqueue’: net/sched/sch_drr.c:359:11: warning: ‘err’ may be used uninitialized in this function [-Wmaybe-uninitialized] net/sched/sch_qfq.c: In function ‘qfq_enqueue’: net/sched/sch_qfq.c:885:11: warning: ‘err’ may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: David S. Miller <davem@davemloft.net>
