net: phy: Guard against the presence of a netdev
A prerequisite for PHYLIB to work in the absence of a struct net_device
is to not access pointers to it.
Changes are needed in the following areas:
- Printing: In some places netdev_err was replaced with phydev_err.
- Incrementing reference count to the parent MDIO bus driver: If there
is no net device, then the reference count should definitely be
incremented since there is no chance that it was an Ethernet driver
who registered the MDIO bus.
- Sysfs links are not created in case there is no attached_dev.
- No netif_carrier_off is done if there is no attached_dev.
