Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.

Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX
for consistency.
