net: hns3: add one parameter for function hns3_nic_maybe_stop_tx()

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

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

Function hns3_nic_net_xmit() and functioin hns3_nic_maybe_stop_tx() both
get ring pointer from priv->ring[]. According to opinion of community to
reduce this kind of operation, this patch adds parameter ring for function
hns3_nic_maybe_stop_tx().
