Subject: [Patch net-next 2/2] net_sched: fix another regression in cls_tcindex

Clearly the following change is not expected:

	-       if (!cp.perfect && !cp.h)
	-               cp.alloc_hash = cp.hash;
	+       if (!cp->perfect && cp->h)
	+               cp->alloc_hash = cp->hash;

Fixes: commit 331b72922c5f58d48fd ("net: sched: RCU cls_tcindex")
