net: hns3: disable loopback setting in hclge_mac_init

Browse Source 
If the selftest and reset are performed at the same time, the loopback
setting may be still in the enable state after the reset. As a result,
packets cannot be sent out.

This patch fixes this issue by disabling loopback in hclge_mac_init.
