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

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: 79664077 ("net: hns3: support RXD advanced layout")
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")
