[IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_dev

Browse Source 
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.
