cls_u32: add missing RCU annotation.
[ Upstream commit 058a6c033488494a6b1477b05fe8e1a16e344462 ]
In a couple of points of the control path, n->ht_down is currently
accessed without the required RCU annotation. The accesses are
safe, but sparse complaints. Since we already held the
rtnl lock, let use rtnl_dereference().

Fixes: de5df63228fc ("net: sched: cls_u32 changes to knode must appear atomic to readers")
