[net-next 02/16] net/mlx5e: Skip redundant checks when providing NUD lastuse feedback

[Saeed Mahameed]

From: Roi Dayan <r...@mellanox.com>

It's redundant to continue the loop if we found one flow whose lastuse value
being newer than the last one we reported, since this is enough for us to
trigger a NUD update (neigh_event_send()).
