net/fec: fix the .remove code

Browse source

The .remove code is broken in several ways.
 - mdiobus_unregister() is called twice for the same object in case of dual FEC
 - phy_disconnect() is being called when the PHY is already disconnected
 - the requested IRQ(s) are not freed
 - fec_stop() is being called with the inteface already stopped

 All of those lead to kernel crashes if the remove function is actually used.
