net: hns3: disable phy loopback setting in hclge_mac_start_phy

Browse Source 
[ Upstream commit 472497d0bdae890a896013332a0b673f9acdf2bf ]

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().
