net/mlx5e: TC, Remove mirror and ct limitation
Mirror action before a ct nat action was not supported when only
chain was restored on misses. As to work around that limitation,
ct action was reordered to be first (so if hw misses on ct
action, packet wasn't modified). This reordering wasn't possible
if there was mirror action before the ct nat action, as we had to
mirror the packet before the nat operation.
Now that the misses continue from the relevant tc ct action
in software and ct action is no longer reordered, this case
is supported.
Remove this limitation.
