Subject: net/hns3: separate flow RSS config from RSS conf

[ upstream commit b93ad0cc7677881911e5fc3baa89e0a0bbd73c48 ]

Some RSS fields in struct hns3_rss_conf (e.g. conf, queue,
valid) are only used when create RSS flow rule, which is
unnecessary for RSS configuration information from ethdev
ops. This patch removes these fields from hns3_rss_conf
and add a new struct hns3_flow_rss_conf as rte flow
RSS filter list node element.
