[ Upstream commit 1c12493809924deda6c0834cb2f2c5a6dc786390 ]
When there is a PHY, the driver needs to complete some operations through
MDIO during reset reinitialization, so HCLGE_STATE_CMD_DISABLE is more
suitable than HCLGE_STATE_RST_HANDLING to prevent the MDIO operation from
being sent during the hardware reset.
Fixes: b50ae26c57cb ("net: hns3: never send command queue message to IMP when reset)
