net: dsa: Do not clobber PHY link outside of state machine

Calling phy_read_status() means that we may call into genphy_read_status() which in turn will use genphy_update_link() which can make changes to phydev->link outside of the state machine's state transitions. This is an invalid behavior that is now caught as of 811a919135b9 ("phy state machine: failsafe leave invalid RUNNING state") Reported-by: Zefir Kurtisi <zefir.kurtisi@neratec.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.
