net: hns3: fix for cleaning ring problem

Browse source

The head or tail in hardware is not longer valid when resetting,
current hns3_clear_all_ring use them to clean the ring, which
will cause problem during resetting.

This patch fixes it by using next_to_use and next_to_clean in
the ring struct.
