[NETFILTER]: nf_conntrack: clean up a few header files

- Remove declarations of non-existing variables and functions - Move helper init/cleanup function declarations to nf_conntrack_helper.h - Remove unneeded __nf_conntrack_attach declaration and make it static Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
