Subject: net/mlx4_en: really allow to change RSS key

From: Eric Dumazet <edumazet@google.com>

[ Upsteam commit 4671fc6d47e0a0108fe24a4d830347d6a6ef4aa7 ]

When changing rss key, we do not want to overwrite user provided key
by the one provided by netdev_rss_key_fill(), which is the host random
key generated at boot time.
