phylib: fixes for PHY_RESUMING state changes
The PHY_HALTED state disables phydev->link, but the link will not be
updated upon entering PHY_RESUMING. Add a call to phy_read_status() to
update the link before entering PHY_RUNNING. If the link is not up at
this point, enter the PHY_NOLINK state instead.
Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to
netif_carrier_on() and phydev->adjust_link() are missing. Add the calls
similar to the other transitions to PHY_RUNNING.
