[PATCH net-next 09/15] net/mlx5: LAG, drop MLX5_MAX_PORTS scratch array from device rescan

[Tariq Toukan]

From: Shay Drory <shayd@xxxxxxxxxx>

mlx5_lag_rescan_devices_locked_filter() collected the participating LAG
members into a fixed-size devs[MLX5_MAX_PORTS] array only to iterate
over it a second time for the rescan calls. Drop the scratch array and
re-walk the members directly with mlx5_lag_for_each().

This removes another dependency on the compile-time MLX5_MAX_PORTS bound
with no functional change.
