net: sched: fix unsued cpu variable
kbuild test robot reported an unused variable cpu in cls_u32.c
after the patch below. This happens when PERF and MARK config
variables are disabled
Fix this is to use separate variables for perf and mark
and define the cpu variable inside the ifdef logic.
Fixes: 459d5f626da7 ("net: sched: make cls_u32 per cpu")'
