4.2-stable review patch. If anyone has any objections, please let me know.

From: Eric Dumazet <eduma...@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.
Fixes: 947cbb0ac242 ("net/mlx4_en: Support for configurable RSS hash function")
