common/mlx5: fix MAC addresses flush

mlx5_nl_mac_addr_flush should flush all allocated MAC
addresses.

The MAC addresses array size should be of size
MLX5_MAX_MAC_ADDRESSES, but currently we return without
flushing the addresses if size is MLX5_MAX_MAC_ADDRESSES.

This was fixed by not allowing an array larger than
MLX5_MAX_MAC_ADDRESSES.
