> Commit 55917a21d0cc ("netfilter: x_tables: add context to know if
> extension runs from nft_compat") introduced a member nft_compat to
> xt_tgchk_param structure.
> But it didn't set it's value for ipt_init_target. With unexpected
> value in par.nft_compat, it may return unexpected result in some
> target's checkentry.
> This patch is to set all it's fields as 0 and only initialize the
> non-zero fields in ipt_init_target.
> As Wang Cong's suggestion, fix it by setting all it's fields as
> 0 and only initializing the non-zero fields.
