net: hns3: Removes unnecessary check when clearing TX/RX rings
Our code will ensure that hns3_clear_tx_ring is not used to cleared
RX rings and hns3_clear_rx_ring is not used to cleared TX rings. So
the ring type check is unnecessary.
Fixes: 76ad4f0ee747 ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC")
