[IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_dev
Now that multiple loopback devices are becoming possible it makes the code a little cleaner and more maintainable to test if a deivice is th a loopback device by testing dev->flags & IFF_LOOPBACK instead of dev == loopback_dev.
