From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

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")
