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.
