Subject: [PATCH net-next 09/12] net: hns3: adjust the use of alloc_tqps and num_tqps

The alloc_tqps field of struct hclge_vport represents the total number
of tqps allocated to the vport. The num_tqps of struct
hnae3_knic_private_info indicates the total number of all enabled tqps,
which needs to be distinguished during use.
