net: ethernet: bcmgenet: fix fixed-link phydev leaks
Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on probe errors and on driver unbind.
Note that we're still leaking any fixed-link PHY registered in the
non-OF probe path.
Fixes: 9abf0c2b717a ("net: bcmgenet: use the new fixed PHY helpers")
