Subject: net: hns3: disable phy loopback setting in hclge_mac_start_phy
Patch-mainline: v5.13-rc1
Git-commit: 472497d0bdae890a896013332a0b673f9acdf2bf
References: bsc#1104353 FATE#326415

If selftest and reset are performed at the same time, the phy
loopback setting may be still in enable state after the reset,
and device cannot link up. So fix this issue by disabling phy
loopback before phy_start().
