net/hns3: fix data type to store queue number

Currently, u8 type variable is used to control to release fake queues in
hns3_fake_rx/tx_queue_config function. Although there is no case in
which more than 256 fake queues are created in hns3 network engine, it
is unreasonable to compare u8 variable with u16 variable.
