net: ucc_geth: drop acquired references in probe error path and remove

The ucc_geth_probe function assigns to ug_info->tbi_node and
ug_info->phy_node a value returned by of_parse_phandle which returns a
new reference. Put this reference again in the error path of
ucc_geth_probe and when removing the device.
