rtnl: simplify error return path in rtnl_create_link()
There is only one possible error path which reaches the err label, so return ERR_PTR(-ENOMEM) directly if alloc_netdev_mqs() fails. This also allows to omit the err variable. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
