Adrien Mazarguil 56d1cd47ff net/mlx4: revert flow API RSS support
This reverts commit d7769c7c08.

Existing RSS features rely on experimental Verbs provided by Mellanox OFED.

In order to replace this dependency with standard distribution packages,
RSS support must be temporarily removed to be re-implemented using a
different API.

Removing support for the RSS flow rule action is the first step toward this
goal.
