openvswitch: delete the unncessary skb_pull_rcsum call in ovs_ct_nat_execute
The calls to ovs_ct_nat_execute() are as below:
ovs_ct_execute()
ovs_ct_lookup()
__ovs_ct_lookup()
ovs_ct_nat()
ovs_ct_nat_execute()
ovs_ct_commit()
__ovs_ct_lookup()
ovs_ct_nat()
ovs_ct_nat_execute()
and since skb_pull_rcsum() and skb_push_rcsum() are already
called in ovs_ct_execute(), there's no need to do it again
in ovs_ct_nat_execute().
