net: move the nat function to nf_nat_ovs for ovs and tc
There are two nat functions are nearly the same in both OVS and TC code, (ovs_)ct_nat_execute() and ovs_ct_nat/tcf_ct_act_nat(). This patch creates nf_nat_ovs.c under netfilter and moves them there then exports nf_ct_nat() so that it can be shared by both OVS and TC, and keeps the nat (type) check and nat flag update in OVS and TC's own place, as these parts are different between OVS and TC. Note that in OVS nat function it was using skb->protocol to get the proto as it already skips vlans in key_extract(), while it doesn't in TC, and TC has to call skb_protocol() to get proto. So in nf_ct_nat_execute(), we keep using skb_protocol() which works for both OVS and TC contrack.
