netfilter: Add nf_hook_state initializer function.
This way we can consolidate where we setup new nf_hook_state objects, to make sure the entire thing is initialized. The only other place an nf_hook_object is instantiated is nf_queue, wherein a structure copy is used. Signed-off-by: David S. Miller <davem@davemloft.net>
