net: hns3: remove struct hns3_nic_ring_data in hns3_enet module

BugLink: https://launchpad.net/bugs/1859261
Only the queue_index field in struct hns3_nic_ring_data is
used, other field is unused and unnecessary for hns3 driver,
so this patch removes it and move the queue_index field to
hns3_enet_ring.

This patch also removes an unused struct hns_queue declaration.
