From: Yunsheng Lin <linyunsheng at huawei.com>

BugLink: https://launchpad.net/bugs/1893711

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.
