Subject: net/sched/sch_red.c: work around gcc-4.4.4 anon union initializer issue

gcc-4.4.4 (at lest) has issues with initializers and anonymous unions:

net/sched/sch_red.c: In function 'red_dump_offload':
net/sched/sch_red.c:282: error: unknown field 'stats' specified in initializer
net/sched/sch_red.c:282: warning: initialization makes integer from pointer without a cast
net/sched/sch_red.c:283: error: unknown field 'stats' specified in initializer
net/sched/sch_red.c:283: warning: initialization makes integer from pointer without a cast
net/sched/sch_red.c: In function 'red_dump_stats':
net/sched/sch_red.c:352: error: unknown field 'xstats' specified in initializer
net/sched/sch_red.c:352: warning: initialization makes integer from pointer without a cast

Work around this.
