tg3: clean up PHYLIB resources on probe failure

In the Linux kernel, the following vulnerability has been resolved:

tg3: clean up PHYLIB resources on probe failure

tg3_get_invariants() can register an MDIO bus and connect a PHY for
USE_PHYLIB devices. If tg3_init_one() later fails, its common error path
releases the mappings and netdev without undoing those PHYLIB resources.

Disconnect the PHY and unregister the MDIO bus before the remaining
teardown. Guard PHY cleanup with USE_PHYLIB to match tg3_phy_init(), and
call tg3_mdio_fini() unconditionally to match tg3_mdio_init(). The existing
IS_CONNECTED and MDIOBUS_INITED flags make both helpers safe when
initialization only completed partially.

This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
