Zero-initialize the dump struct before selective assignment to avoid
leaking stack padding in netlink replies. This matches other actions
(e.g. act_connmark) that zero-init their dump structs.

I do not see a bug to fix, current code is fine.
act_connmark problem was that "struct tc_connmark" had a 16bit hole.
No such issue for struct tc_gate.
