Marcelo Ricardo Leitner 2ae0f0a409 net/sched: act_ct: handle DNAT tuple collision 
[ Upstream commit 13c62f5371e3eb4fc3400cfa26e64ca75f888008 ]

This this the counterpart of 8aa7b526dc ("openvswitch: handle DNAT
tuple collision") for act_ct. From that commit changelog:

"""
With multiple DNAT rules it's possible that after destination
translation the resulting tuples collide.

...

Netfilter handles this case by allocating a null binding for SNAT at
egress by default.  Perform the same operation in openvswitch for DNAT
if no explicit SNAT is requested by the user and allocate a null binding
for SNAT for packets in the "original" direction.
"""
