net sched: fix kernel leak in act_police

While reviewing commit 1c40be12f7d8ca1d387510d39787b12e512a7ce8, I
 audited other users of tc_action_ops->dump for information leaks.

 That commit covered almost all of them but act_police still had a leak.

 opt.limit and opt.capab aren't zeroed out before the structure is
 passed out.

 This patch uses the C99 initializers to zero everything unused out.
