iptables: fix error reporting with wrong/missing arguments

This patch fixes wrong error reporting when arguments are missing:

# iptables -I INPUT -m state --state
iptables v1.4.2-rc1: Unknown arg `(null)'
Try `iptables -h' or 'iptables --help' for more information.

or wrong:

# iptables -I INPUT -m state --xyz
iptables v1.4.2-rc1: Unknown arg `(null)'
Try `iptables -h' or 'iptables --help' for more information.
