[PATCH net 1/3] net: ethernet: ixgbe: don't propagate -ENODEV from ixgbe_mii_bus_init()

From: Bartosz Golaszewski <redacted>

It's a valid use-case for ixgbe_mii_bus_init() to return -ENODEV - we
still want to finalize the registration of the ixgbe device. Check the
error code and don't bail out if err == -ENODEV.

This fixes an issue on C3000 family of SoCs where four ixgbe devices
share a single MDIO bus and ixgbe_mii_bus_init() returns -ENODEV for
three of them but we still want to register them.

Fixes: 09ef193fef7e ("net: ethernet: ixgbe: check the return value of ixgbe_mii_bus_init()")
