[ Upstream commit dd3fddb82780bfa24124834edd90bbc63bd689cc ]
This is the same check as LAG mode checks if to enable lag.
This will fix adding peer miss rules if lag is not supported
and even an incorrect rules in socket direct mode.
Also fix the incorrect comment on mlx5_get_next_phys_dev() as flow #1
doesn't exists.
Fixes: ac004b832128 ("net/mlx5e: E-Switch, Add peer miss rules")
