Subject: [PATCH 21/25] net/hns3: remove redundant RSS tuple field

The 'rss_tuple_fields' in struct struct hns3_rss_conf::rss_tuple_sets is
redundant. Because the enabled RSS tuple in PMD is already managed by
the 'types' in struct hns3_rss_conf::conf. This patch removes this
redundant variable.

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