netfilter: ip6_tables: ip6t_ext_hdr is now static inline
We may hit this in xt_LOG:
net/built-in.o:xt_LOG.c:function dump_ipv6_packet:
error: undefined reference to 'ip6t_ext_hdr'
happens with these config options:
CONFIG_NETFILTER_XT_TARGET_LOG=y
CONFIG_IP6_NF_IPTABLES=m
ip6t_ext_hdr is fairly small and it is called in the packet path.
Make it static inline.
