When an indirect action was created with an RSS action configured to hash on both source and destination L3 addresses (or L4 ports), it caused shared hrxq to be configured to hash only on destination address (or port). This patch fixes this behavior by refining RSS types specified in configuration before calculating hash types used for hrxq. Refining RSS types removes *_SRC_ONLY and *_DST_ONLY flags if they are both set.
