Subject: net: hns3: minor refactor for hns3_rx_checksum
Patch-mainline: v5.2-rc1
Git-commit: a4d2cdcbb878d4d5828cd4124104c330d2817211
References: bsc#1104353 FATE#326415 bsc#1135052

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.
