Subject: [PATCH V2 net-next 05/12] net: hns3: minor refactor for hns3_rx_checksum

From: Yunsheng Lin <linyunsheng@...wei.com>

Change the parameters of hns3_rx_checksum to be more specific to
what is used internally, rather than passing in a pointer to the
whole hns3_desc. Reduces duplicate code and bring this function
inline with the approach used in hns3_set_gro_param.
