net/ipforward: fix typo in ipv4_dev_forward

Browse Source 
f_domain is used to determine protocol family when CONFIG_NET_IPv4 and CONFIG_NET_IPv6 are both defined, but not correctly used in ipv4_dev_forward because of typo (there's not a config named CONFIG_NET_IPv5) which may cause IPv4 packets to be forwarded as IPv6.
