Subject: Fix #1492: logger: print timestamps only if we have one
X-Git-Url: https://git.proxmox.com/?p=pve-firewall.git;a=commitdiff_plain;h=2388cab121beef58bb20b6b2275379304c6de737;hp=2388cab121beef58bb20b6b2275379304c6de737

Fix #1492: logger: print timestamps only if we have one

There's no guarantee that there's a timestamp in an skb, so
nflog_get_timestamp can fail.
