Kevin Bowling 1ad999a1c7 mlx4en: Use the common RSS key for programming and queries
Replace the private fixed key with rss_getkey().  Copy the common byte
stream directly into the RSS queue-pair context and use the same helper
for SIOCGIFRSSKEY, so hardware programming and hn's query agree.

Change the helper to fill caller-owned storage instead of returning a
pointer to a static key.  Check the fixed hardware and ioctl buffer sizes
at compile time.  Leave RSS masks and queue steering unchanged.
