rG709d7cf3039f: ixgbe: Use the common RSS key without options RSS
Summary
Use rss_getkey() for PF and VF RSS programming even when options RSS is
not configured.  The common key is available independently of RSS queue
placement and is also used by software hashing.  Generating a private key
on each initialization defeats that agreement and changes receive hashes
across resets.

Leave hash-field selection and indirection-table placement unchanged.
82599 and X540 VFs retain their PF-owned RSS configuration.
