[NETFILTER]: nf_nat: pass manip type instead of hook to nf_nat_setup_info

nf_nat_setup_info gets the hook number and translates that to the
manip type to perform. This is a relict from the time when one
manip per hook could exist, the exact hook number doesn't matter
anymore, its converted to the manip type. Most callers already
know what kind of NAT they want to perform, so pass the maniptype
in directly.
