Because the macro named RTE_FLOW_ERROR_TYPE_ACTION_CONF indicates a
action configuration and the macro named RTE_FLOW_ERROR_TYPE_ACTION
indicates a specific action, the driver needs to return
RTE_FLOW_ERROR_ACTION_CONF type and notify the user when a RSS
configuration is invalid with actions list in the internal function
named hns3_parse_rss_filter called by the '.validate' ops implementation
function named hns3_flow_validate.

Besides, this patch removes some unnecessary judgment lines in
hns3_parse_rss_filter.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
