commit 21c167aa0ba943a7cac2f6969814f83bb701666b upstream.
The tc action act_ctinfo was using shared stats, fix it to use percpu stats since bstats_update() must be called with locks or with a percpu pointer argument.
tdc results: 1..12 ok 1 c826 - Add ctinfo action with default setting ok 2 0286 - Add ctinfo action with dscp ok 3 4938 - Add ctinfo action with valid cpmark and zone ok 4 7593 - Add ctinfo action with drop control ok 5 2961 - Replace ctinfo action zone and action control ok 6 e567 - Delete ctinfo action with valid index ok 7 6a91 - Delete ctinfo action with invalid index ok 8 5232 - List ctinfo actions ok 9 7702 - Flush ctinfo actions ok 10 3201 - Add ctinfo action with duplicate index ok 11 8295 - Add ctinfo action with invalid index ok 12 3964 - Replace ctinfo action with invalid goto_chain control
