net/sched/sch_prio.c: work around gcc-4.4.4 union initializer issues

gcc-4.4.4 has problems witn anon union initializers.  Work around this.

net/sched/sch_prio.c: In function 'prio_dump_offload':
net/sched/sch_prio.c:260: error: unknown field 'stats' specified in initializer
net/sched/sch_prio.c:260: warning: initialization makes integer from pointer without a cast
net/sched/sch_prio.c:261: error: unknown field 'stats' specified in initializer
net/sched/sch_prio.c:261: warning: initialization makes integer from pointer without a cast
