[PATCH] extensions: libipt_LOG: Avoid to print the default log level in the translation

[Laura Garcia Liebana <nevola@gmail.com>]

Avoid to print the log level in the translation when the level is the
default value.

Example:

$ sudo iptables-translate -t filter -A INPUT -m icmp ! --icmp-type 10 -j LOG
nft add rule ip filter INPUT icmp type != router-solicitation counter log
