net_sched: act_ctinfo: use atomic64_t for three counters

Browse source

Commit 21c167aa0b ("net/sched: act_ctinfo: use percpu stats")
missed that stats_dscp_set, stats_dscp_error and stats_cpmark_set
might be written (and read) locklessly.

Use atomic64_t for these three fields, I doubt act_ctinfo is used
heavily on big SMP hosts anyway.
