net/mlx5: fix shared RSS action release

As shared RSS action will be shared by multiple flows, the action
is created as global standalone action and managed only by the
relevant shared action management functions.

Currently, hrxqs will be created by shared RSS action or general
queue action. For hrxqs created by shared RSS action, they should
also only be released with shared RSS action. It's not correct to
release the shared RSS action hrxqs as general queue actions do
in flow destroy.

This commit adds a new fate action type for shared RSS action to
handle the shared RSS action hrxq release correctly.
