net/mlx5e: Add a check for the return value from mlx5_port_set_eth_ptys
[ Upstream commit 3f8e82a020a5c22f9b791f4ac499b8e18007fbda ]
Since the documentation for mlx5_toggle_port_link states that it should
only be used after setting the port register, we add a check for the
return value from mlx5_port_set_eth_ptys to ensure the register was
successfully set before calling it.
Fixes: 667daedaecd1 ("net/mlx5e: Toggle link only after modifying port parameters")
