net: mdio: octeon: Fix some double free issues
'bus->mii_bus' has been allocated with 'devm_mdiobus_alloc_size()' in the
probe function. So it must not be freed explicitly or there will be a
double free.
Remove the incorrect 'mdiobus_free' in the error handling path of the
probe function and in remove function.
