net: hns3: fix incorrect handling of sctp6 rss tuple

[ Upstream commit ab6e32d ] For DEVICE_VERSION_V2, the hardware only supports src-ip, dst-ip and verification-tag for rss tuple set of sctp6 packet. For DEVICE_VERSION_V3, the hardware supports src-port and dst-port as well. Currently, when user queries the sctp6 rss tuples info, some unsupported information will be showed on V2. So add a check for hardware version when initializing and queries sctp6 rss tuple to fix this issue.
