net/mlx5: fix RSS hash types adjustment

Browse Source 
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.

Fixes: 212d17b6a6 ("net/mlx5: fix missing shared RSS hash types")
