netfilter: log: Fix log-level processing
auto75914331@hushmail.com reports that iptables does not correctly output the KERN_<level>. $IPTABLES -A RULE_0_in -j LOG --log-level notice --log-prefix "DENY in: " result with linux 3.6-rc5 Sep 12 06:37:29 xxxxx kernel: <5>DENY in: IN=eth0 OUT= MAC=....... result with linux 3.5.3 and older: Sep 9 10:43:01 xxxxx kernel: DENY in: IN=eth0 OUT= MAC...... commit 04d2c8c83d0 ("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern") updated the syslog header style but did not update netfilter uses. Do so. Use KERN_SOH and string concatenation instead of "%c" KERN_SOH_ASCII as suggested by Eric Dumazet.
