net: hns3: fix incorrect hw rss hash type of rx packet

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7ORRB


CVE: NA

----------------------------

Currently, the HNS3 driver reports the rss hash type
of each packet based on the rss hash tuples set. It
always reports PKT_HASH_TYPE_L4, without checking the
type of current packet. It's incorrect.
Fixes it by reporting it base on the packet type.

Fixes: 232fc64b ("net: hns3: Add HW RSS hash information to RX skb")
Fixes: ea485867 ("net: hns3: handle the BD info on the last BD of the packet")
