From: Jie Wang <wangjie125@huawei.com>

Currently PF stores its rss parameters in vport structure. VF stores rss
configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters
are same beween PF and VF. The two set of rss parameters are redundent and
may add extra bugfix work.

So this patch creates new common rss parameter struct(hclge_comm_rss_cfg)
to unify PF and VF rss configurations.

These new structures will be used to unify rss configurations in PF and VF
rss APIs in next patches.
