[PATCH nf] netfilter: ebt_nflog: fix unexpected truncated packet

[Liping Zhang <zlpnobody@163.com>]

From: Liping Zhang <zlpnobody@gmail.com>

"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")
