mq, mqprio: Use gnet_stats_add_queue().
gnet_stats_add_basic() and gnet_stats_add_queue() add up the statistics so they can be used directly for both the per-CPU and global case. gnet_stats_add_queue() copies either Qdisc's per-CPU gnet_stats_queue::qlen or the global member. The global gnet_stats_queue::qlen isn't touched in the per-CPU case so there is no need to consider it in the global-case. In the per-CPU case, the sum of global gnet_stats_queue::qlen and the per-CPU gnet_stats_queue::qlen was assigned to sch->q.qlen and sch->qstats.qlen. Now both fields are copied individually.
