Subject: netfilter: ebt_nflog: fix unexpected truncated packet
Patch-mainline: v4.13-rc1
Git-commit: 91af6ba7ff16bd7e5919aedfe70aad73a3375619
References: bsc#1076830
"struct nf_loginfo li;" is a local variable, so we should set the flags
to 0 explicitly, else, packets maybe truncated unexpectedly when copied
to the userspace.
Fixes: 7643507fe8b5 ("netfilter: xt_NFLOG: nflog-range does not truncate packets")
