net: sched: red: delay destroying child qdisc on replace
Move destroying of the old child qdisc outside of the sch_tree_lock() section. This should improve the software qdisc replace but is even more important for offloads. Firstly calling offloads under a spin lock is best avoided. Secondly the destroy event of existing child would have been sent to the offload device before the replace, causing confusion.
