net/hns3: fix variable type mismatch

[ upstream commit 1bbac8785cdf51bc6c5005c6754eab4d517cc4b0 ]

Loop conditions are compared with different variable types,
which may cause overflow risks.

Fixes: 67d0103 ("net/hns3: adjust data type of some variables")
Fixes: 6ee07e3 ("net/hns3: fix insecure way to query MAC statistics")
