net/mlx5e: Disable loopback self-test on multi-PF netdev
In Multi-PF (Socket Direct) configurations, when a loopback packet is
sent through one of the secondary devices, it will always be received
on the primary device. This causes the loopback layer to fail in
identifying the loopback packet as the devices are different.
To avoid false test failures, disable the loopback self-test in
Multi-PF configurations.
