We clear STATE_DOWN bit of hdev state when starting net, but do not set
it again when stopping net. It causes that the net is down, but hdev state
is still up. STATE_DOWN bit of hdev state should be set when stopping net.

For marvell phy m88e1510, bit SUPPORTED_FIBRE of phydev->supported
is default on. Both phy_resume() and phy_suspend() will check the
SUPPORTED_FIBRE bit and write register of fibre page.

Currently in hns3 driver, the SUPPORTED_FIBRE bit will be cleared
after phy_connect_direct() finished. Because phy_resume() is called
in phy_connect_direct(), and phy_suspend() is called when disconnect
phy device, so the operation for fibre page register is not symmetrical.
It will cause phy link issue when reload hns3 driver.
