Subject: net: hns3: Removes unnecessary check when clearing TX/RX rings
Patch-mainline: v4.18-rc1
Git-commit: 6986df9686c55464b0fa0f36a02f4da81d99a3b1
References: bsc#1104353 FATE#326415

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")
