net: hns3: disable phy loopback setting in hclge_mac_start_phy
[ Upstream commit 472497d ] 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().
