net: hns3: fix ETS bandwidth validation bug

[ Upstream commit c2d56897819338eb0ba8b93184f7d10329b36653 ]

Some device only support 4 TCs, but the driver check the total
bandwidth of 8 TCs, so may cause wrong configurations write to
the hw.

This patch uses hdev->tc_max to instead HNAE3_MAX_TC to fix it.
