Subject: [PATCH] Revert "net: ethernet: ixgbe: check the return value of ixgbe_mii_bus_init()"

This reverts commit 09ef193fef7efb0175a04634853862d717adbb95.

For C3000 family of SoCs, they have four ixgbe devices sharing a single MDIO bus.
ixgbe_mii_bus_init() returns -ENODEV for other three devices. The propagation
of the error code makes other three ixgbe devices unregistered.
