Subject: [PATCH] net/mlx5e: Lag, Fix fib_info pointer assignment
Referenced change incorrectly sets single path fib_info even when LAG is
not active. Fix it by moving call to mlx5_lag_fib_set() into conditional
that verifies LAG state.
Fixes: ad11c4f1d8fd ("net/mlx5e: Lag, Only handle events from highest priority multipath entry")
